Remove mentions of the FSF address Since using addresses that might change is something that finally the FSF acknowledge as a plausible scenario (after changing address twice), the license blurb in the source files should use the URI for getting the license in case the library did not come with it. Not that URIs cannot possibly change, but at least it's easier to set up a redirection at the same place.

Improve repaint functions It is sometimes useful to be able to have better control on when a repaint function is called. Currently, all repaint functions are called prior to the stages update phase of the frame processing. We can introduce flags to represent the point in the frame update process in which we wish Clutter called the repaint function. As a bonus, we can also add a flag that causes adding a repaint function to spin the master clock.

Deprecate clutter_threads_init() GLib deprecated g_thread_init(), and threading support is initialized by GObject, so Clutter already runs with threading support enabled. We can drop the clutter_threads_init() call requirement, and initialize the Big Clutter Lock™ on clutter_init(). This reduces the things that have to be done when dealing with threads with Clutter, and the things that can possibly go wrong.

Move examples from tests/interactive to a new top-level The example code that is meant to be XIncluded into the API reference should not be part of the interactive test suite: it's code that it is meant to be used as a reference implementation - whereas the interactive test suite should be allowed to be lean and test behaviour even in nasty ways. In short: the test suite should not be the place where we show off idiomatic code for educational purposes.

Implement multi-backend support The Clutter backend split is opaque enough that should allow us to just build all possible backends inside the same shared object, and select the wanted backend at initialization time. This requires some work in the build system, as well as the initialization code, to remove duplicate functions that might cause conflicts at build and link time. We also need to defer all the checks of the internal state of the platform-specific API to run-time type checks.

Use a single master "clock" to drive timelines Currently, all timelines install a timeout inside the TimeoutPool they share. Every time the main loop spins, all the timeouts are updated. This, in turn, will usually lead to redraws being queued on the stages. This behaviour leads to the potential starvation of timelines and to excessive redraws. One lesson learned from the games developers is that the scenegraph should be prepared in its entirety before the GL paint sequence is initiated. This means making sure that every ::new-frame signal handler is called before clutter_redraw() is invoked. In order to do so a TimeoutPool is not enough: we need a master clock. The clock will be responsible for advancing all the active timelines created inside a scene, but only when the stage is being redrawn. The sequence is: + queue_redraw() is invoked on an actor and bubbles up to the stage + if no redraw() has already been scheduled, install an idle handler with a known priority + inside the idle handler: - advance the master clock, which will in turn advance every playing timeline by the amount of milliseconds elapsed since the last redraw; this will make every playing timeline emit the ::new-frame signal - queue a relayout - call the redraw() method of the backend This way we trade multiple timeouts with a single frame source that only runs if a timeline is playing and queues redraws on the various stages.

profiling: Adds initial UProf support across clutter UProf is a small library that aims to help applications/libraries provide domain specific reports about performance. It currently provides high precision timer primitives (rdtsc on x86) and simple counters, the ability to link statistics between optional components at runtime and makes report generation easy. This adds initial accounting for: - Total mainloop time - Painting - Picking - Layouting - Idle time The timing done by uprof is of wall clock time. It's not based on stochastic samples we simply sample a counter at the start and end. When dealing with the complexities of GPU drivers and with various kinds of IO this form of profiling can be quite enlightening as it will be able to represent where your application is blocking unlike tools such as sysprof. To enable uprof accounting you must configure Clutter with --enable-profile and have uprof-0.2 installed from git://git.moblin.org/uprof If you want to see a report of statistics when Clutter applications exit you should export CLUTTER_PROFILE_OUTPUT_REPORT=1 before running them. Just a final word of caution; this stuff is new and the manual nature of adding uprof instrumentation means it is prone to some errors when modifying code. This just means that when you question strange results don't rule out a mistake in the instrumentation. Obviously though we hope the benfits out weigh e.g. by focusing on very key stats and by having automatic reporting.

Store the motion event deliver flag in ClutterStage Once upon a time, the land of Clutter had a stage singleton. It was created automatically at initialization time and stayed around even after the main loop was terminated. The singleton was content in being all there was. There also was a global API to handle the configuration of the stage singleton that would affect the behaviour on other classes, signals and properties. Then, an evil wizard came along and locked the stage singleton in his black tower, and twisted it until it was possible to create new stages. These new stages were pesky, and didn't have the same semantics of the singleton: they didn't stay around when closed, or terminate the main loop on delete events. The evil wizard also started moving all the stage-related API from the global context into class-specific methods. Finally, the evil wizard cast a spell, and the stage singleton was demoted to creation on demand - and until somebody called the clutter_stage_get_default() function, the singleton remained in a limbo of NULL pointers and undefined memory areas. There was a last bit - literally - of information still held by the global API; a tiny, little flag that disabled per-actor motion events. The evil wizard added private accessors for it, and stored it inside the stage private structure, in preparation for a deprecation that would come in a future development cycle. The evil wizard looked down upon the land of Clutter from the height of his black tower; the lay of the land had been reshaped into a crucible of potential, and the last dregs of the original force of creation were either molted into new, useful shapes, or blasted away by the sheer fury of his will. All was good.

Implement multi-backend support The Clutter backend split is opaque enough that should allow us to just build all possible backends inside the same shared object, and select the wanted backend at initialization time. This requires some work in the build system, as well as the initialization code, to remove duplicate functions that might cause conflicts at build and link time. We also need to defer all the checks of the internal state of the platform-specific API to run-time type checks.

Fix include location for cogl-pango.h In Cogl, cogl-pango.h has moved to <cogl-pango/cogl-pango.h>. When using the experimental 2.0 API (which Clutter does) it is no longer possible to include it under the old name of <cogl/cogl-pango.h> so we need to update the include location.

Add the ability to set the text direction The direction of the text depends on the locale, and it is the basic setting needed to enable internationalization of user interfaces. This commit allows setting the direction of the PangoContext instance used by Clutter by using the CLUTTER_TEXT_DIRECTION environment variable, or by passing the --clutter-text-direction command line argument. Valid values are: ltr - for left-to-right locales rtl - for right-to-left locales The default is LTR. Ideally, this should be a value set by the localization teams on the PO file, but this step requires some build system surgery to allow the translation of the Clutter strings.

debug: Split debugging notes from behavioural modifiers Some of the ClutterDebugFlags are not meant as a logging facility: they actually change Clutter's behaviour at run-time. It would be useful to have this distinction ratified, and thus split ClutterDebugFlags into two: one DebugFlags for logging facilities and another set of flags for behavioural changes. This split is warranted because: • it should be possible to do "CLUTTER_DEBUG=all" and only have log messages on the output • it should be possible to use behavioural modifiers even on a Clutter that has been compiled without debugging messages support The commit adds two new debugging flags: ClutterPickDebugFlags - controlled by the CLUTTER_PICK environment variable ClutterPaintDebugFlags - controlled by the CLUTTER_PAINT environment variable The PickDebugFlags are: nop-picking dump-pick-buffers While the PaintDebugFlags is: disable-swap-events The mechanism is equivalent to the CLUTTER_DEBUG environment variable, but it does not depend on the debug level selected when configuring and compiling Clutter.

Optimize culling by doing culling in eye-coordinates This implements a variation of frustum culling whereby we convert screen space clip rectangles into eye space mini-frustums so that we don't have to repeatedly transform actor paint-volumes all the way into screen coordinates to perform culling, we just have to apply the modelview transform and then determine each points distance from the planes that make up the clip frustum. By avoiding the projective transform, perspective divide and viewport scale for each point culled this makes culling much cheaper.

actor: add oob-transform opt to catch out-of-band transforms Out-of-band transforms are considered to be all actor transforms done directly with the Cogl API instead of via ClutterActor::apply_transform. By running with CLUTTER_DEBUG=oob-transform then Clutter will explicitly try to detect when un-expected transforms have been applied to the modelview matrix stack. Out-of-band transforms can lead to awkward bugs in Clutter applications because Clutter itself doesn't know about them and this can disrupt Clutter's input handling and calculations of actor paint-volumes which can lead to visual artifacts.

static const GDebugKey clutter_paint_debug_keys[] = {
Adds initial clipped redraw support to Clutter A new (internal only currently) API, _clutter_actor_queue_clipped_redraw can be used to queue a redraw along with a clip rectangle in actor coordinates. This clip rectangle propagates up to the stage and clutter backend which may optionally use the information to optimize stage redraws. The GLX backend in particular may scissor the next redraw to the clip rectangle and use GLX_MESA_copy_sub_buffer to present the stage subregion. The intention is that any actors that can naturally determine the bounds of updates should queue clipped redraws to reduce the cost of updating small regions of the screen. Notes: » If GLX_MESA_copy_sub_buffer isn't available then the GLX backend ignores any clip rectangles. » queuing multiple clipped redraws will result in the bounding box of each clip rectangle being used. » If a clipped redraw has a height > 300 pixels then it's promoted into a full stage redraw, so that the GPU doesn't end up blocking too long waiting for the vsync to reach the optimal position to avoid tearing. » Note: no empirical data was used to come up with this threshold so we may need to tune this. » Currently only ClutterX11TexturePixmap makes use of this new API. This is done via a new "queue-damage-redraw" signal that is emitted when the pixmap is updated. The default handler queues a clipped redraw with the assumption that the pixmap is being painted as a rectangle covering the actors transformed allocation. If you subclass ClutterX11TexturePixmap and change how it's painted you now also need to override the signal handler and queue your own redraw. Technically this is a semantic break, but it's assumed that no one is currently doing this. This still leaves a few unsolved issues with regards to optimizing sub stage redraws that need to be addressed in further work so this can only be considered a stepping stone a this point: » Because we have no reliable way to determine if the painting of any given actor is being modified any optimizations implemented using _clutter_actor_queue_redraw_with_clip must be overridable by a subclass, and technically must be opt-in for existing classes to avoid a change in semantics. E.g. consider that a user connects to the paint signal for ClutterTexture and paints a circle instead of a rectangle. In this case any original logic to queue clipped redraws would be incorrect. » Currently only the implementation of an actor has enough information with which to queue clipped redraws. E.g. It is not possible for generic code in clutter-actor.c to queue a clipped redraw when hiding an actor because actors have no way to report a "paint box". (remember actors can draw outside their allocation and actors with depth may also be projected outside of their allocation) » The current plan is to add a actor_class->get_paint_cuboid() virtual so actors can report a bounding cube for everything they would draw in their current state and use that to queue clipped redraws against the stage by projecting the paint cube into stage coordinates. » Our heuristics for promoting clipped redraws into full redraws to avoid blocking the GPU while we wait for the vsync need improving: » vsync issues aren't relevant for redirected/composited applications so they should use different heuristics. In this case we instead need to trade off the cost of blitting when using glXCopySubBuffer vs promoting to a full redraw and flipping instead.

Store the motion event deliver flag in ClutterStage Once upon a time, the land of Clutter had a stage singleton. It was created automatically at initialization time and stayed around even after the main loop was terminated. The singleton was content in being all there was. There also was a global API to handle the configuration of the stage singleton that would affect the behaviour on other classes, signals and properties. Then, an evil wizard came along and locked the stage singleton in his black tower, and twisted it until it was possible to create new stages. These new stages were pesky, and didn't have the same semantics of the singleton: they didn't stay around when closed, or terminate the main loop on delete events. The evil wizard also started moving all the stage-related API from the global context into class-specific methods. Finally, the evil wizard cast a spell, and the stage singleton was demoted to creation on demand - and until somebody called the clutter_stage_get_default() function, the singleton remained in a limbo of NULL pointers and undefined memory areas. There was a last bit - literally - of information still held by the global API; a tiny, little flag that disabled per-actor motion events. The evil wizard added private accessors for it, and stored it inside the stage private structure, in preparation for a deprecation that would come in a future development cycle. The evil wizard looked down upon the land of Clutter from the height of his black tower; the lay of the land had been reshaped into a crucible of potential, and the last dregs of the original force of creation were either molted into new, useful shapes, or blasted away by the sheer fury of his will.

stage: Maintain the motion event delivery invariants It is possible, by calling clutter_set_motion_events_enabled() prior to the creation of any stage, to control the per-actor motion event delivery flag on each newly created stage. Since we deprecated the global accessor functions in favour of the per-Stage ones, we need to remove the call to clutter_get_motion_events_enabled() inside the ClutterStage instance initialization, and replace it with an internal function. This code will go away when we can finally break API and remove the deprecated functions.

stage: Move _clutter_do_pick to clutter-stage.c This moves the implementation of _clutter_do_pick to clutter-stage.c and renames it _clutter_stage_do_pick. This function can be compared to _clutter_stage_do_update/redraw in that it prepares for and starts a traversal of a scenegraph descending from a given stage. Since it is desirable that this function should have access to the private state of the stage it is awkward to maintain outside of clutter-stage.c. Besides moving _clutter_do_pick this patch is also able to remove the following private state accessors from clutter-stage-private.h: _clutter_stage_set_pick_buffer_valid, _clutter_stage_get_pick_buffer_valid, _clutter_stage_increment_picks_per_frame_counter, _clutter_stage_reset_picks_per_frame_counter and _clutter_stage_get_picks_per_frame_counter.

More ISO C90 warning fixes in Clutter This time, in Clutter core. The ObjC standard library provides a type called 'id', which obviously requires any library to either drop the useful shadowed variable warning or stop using 'id' as a variable name. Yes, it's almost unbearably stupid. Well, at least it's not 'index' in string.h, or 'y2' in math.h.

More ISO C90 warning fixes in Clutter This time, in Clutter core. The ObjC standard library provides a type called 'id', which obviously requires any library to either drop the useful shadowed variable warning or stop using 'id' as a variable name.

[debug] Guard the use of gdk_pixbuf for pick debugging by #ifdef USE_GDKPIXBUF gdk is an optional clutter dependency, so the pick buffer debugging option needs some guards so we don't break, for example, the OSX builds. This also adds a comment for the bit fiddling done on the pick colors used to ensure the pick colors are more distinguished while debugging. (we swap the nibbles of each color component so that pick buffers don't just look black.)

debug: Split debugging notes from behavioural modifiers Some of the ClutterDebugFlags are not meant as a logging facility: they actually change Clutter's behaviour at run-time. It would be useful to have this distinction ratified, and thus split ClutterDebugFlags into two: one DebugFlags for logging facilities and another set of flags for behavioural changes. This split is warranted because: • it should be possible to do "CLUTTER_DEBUG=all" and only have log messages on the output • it should be possible to use behavioural modifiers even on a Clutter that has been compiled without debugging messages support The commit adds two new debugging flags: ClutterPickDebugFlags - controlled by the CLUTTER_PICK environment variable ClutterPaintDebugFlags - controlled by the CLUTTER_PAINT environment variable The PickDebugFlags are: nop-picking dump-pick-buffers While the PaintDebugFlags is: disable-swap-events The mechanism is equivalent to the CLUTTER_DEBUG environment variable, but it does not depend on the debug level selected when configuring and compiling Clutter. The picking and painting debugging flags are initialized at clutter_init() time. http://bugzilla.openedhand.com/show_bug.cgi?id=1991

stage: Move _clutter_do_pick to clutter-stage.c This moves the implementation of _clutter_do_pick to clutter-stage.c and renames it _clutter_stage_do_pick. This function can be compared to _clutter_stage_do_update/redraw in that it prepares for and starts a traversal of a scenegraph descending from a given stage. Since it is desirable that this function should have access to the private state of the stage it is awkward to maintain outside of clutter-stage.c. Besides moving _clutter_do_pick this patch is also able to remove the following private state accessors from clutter-stage-private.h: _clutter_stage_set_pick_buffer_valid, _clutter_stage_get_pick_buffer_valid, _clutter_stage_increment_picks_per_frame_counter, _clutter_stage_reset_picks_per_frame_counter and _clutter_stage_get_picks_per_frame_counter.

static ClutterTextDirection
Add the ability to set the text direction The direction of the text depends on the locale, and it is the basic setting needed to enable internationalization of user interfaces. This commit allows setting the direction of the PangoContext instance used by Clutter by using the CLUTTER_TEXT_DIRECTION environment variable, or by passing the --clutter-text-direction command line argument. Valid values are: ltr - for left-to-right locales rtl - for right-to-left locales The default is LTR. Ideally, this should be a value set by the localization teams on the PO file, but this step requires some build system surgery to allow the translation of the Clutter strings.

profiling: Adds initial UProf support across clutter UProf is a small library that aims to help applications/libraries provide domain specific reports about performance. It currently provides high precision timer primitives (rdtsc on x86) and simple counters, the ability to link statistics between optional components at runtime and makes report generation easy. This adds initial accounting for: - Total mainloop time - Painting - Picking - Layouting - Idle time The timing done by uprof is of wall clock time. It's not based on stochastic samples we simply sample a counter at the start and end. When dealing with the complexities of GPU drivers and with various kinds of IO this form of profiling can be quite enlightening as it will be able to represent where your application is blocking unlike tools such as sysprof. To enable uprof accounting you must configure Clutter with --enable-profile and have uprof-0.2 installed from git://git.moblin.org/uprof If you want to see a report of statistics when Clutter applications exit you should export CLUTTER_PROFILE_OUTPUT_REPORT=1 before running them. Just a final word of caution; this stuff is new and the manual nature of adding uprof instrumentation means it is prone to some errors when modifying code. This just means that when you question strange results don't rule out a mistake in the instrumentation. Obviously though we hope the benfits out weigh e.g. by focusing on very key stats and by having automatic reporting.

profiling: Adds initial UProf support across clutter UProf is a small library that aims to help applications/libraries provide domain specific reports about performance. It currently provides high precision timer primitives (rdtsc on x86) and simple counters, the ability to link statistics between optional components at runtime and makes report generation easy. This adds initial accounting for: - Total mainloop time - Painting - Picking - Layouting - Idle time The timing done by uprof is of wall clock time. It's not based on stochastic samples we simply sample a counter at the start and end. When dealing with the complexities of GPU drivers and with various kinds of IO this form of profiling can be quite enlightening as it will be able to represent where your application is blocking unlike tools such as sysprof. To enable uprof accounting you must configure Clutter with --enable-profile and have uprof-0.2 installed from git://git.moblin.org/uprof If you want to see a report of statistics when Clutter applications exit you should export CLUTTER_PROFILE_OUTPUT_REPORT=1 before running them. Just a final word of caution; this stuff is new and the manual nature of adding uprof instrumentation means it is prone to some errors when modifying code. This just means that when you question strange results don't rule out a mistake in the instrumentation. Obviously though we hope the benfits out weigh e.g. by focusing on very key stats and by having automatic reporting.

profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git

Deprecate clutter_threads_enter()/leave() Acquiring the Clutter lock to mark critical sections is not portable, and not recommended to implement threaded applications with Clutter. The recommended pattern is to use worker threads, and schedule UI updates inside idle or timeout handlers within the main loop. We should enforce this pattern by deprecating the threads_enter()/leave() functions. For compatibility concerns, we need internal API to acquire the main lock during frame processing dispatch. https://bugzilla.gnome.org/show_bug.cgi?id=679450

profiling: Adds initial UProf support across clutter UProf is a small library that aims to help applications/libraries provide domain specific reports about performance. It currently provides high precision timer primitives (rdtsc on x86) and simple counters, the ability to link statistics between optional components at runtime and makes report generation easy. This adds initial accounting for: - Total mainloop time - Painting - Picking - Layouting - Idle time The timing done by uprof is of wall clock time. It's not based on stochastic samples we simply sample a counter at the start and end. When dealing with the complexities of GPU drivers and with various kinds of IO this form of profiling can be quite enlightening as it will be able to represent where your application is blocking unlike tools such as sysprof. To enable uprof accounting you must configure Clutter with --enable-profile and have uprof-0.2 installed from git://git.moblin.org/uprof If you want to see a report of statistics when Clutter applications exit you should export CLUTTER_PROFILE_OUTPUT_REPORT=1 before running them. Just a final word of caution; this stuff is new and the manual nature of adding uprof instrumentation means it is prone to some errors when modifying code. This just means that when you question strange results don't rule out a mistake in the instrumentation. Obviously though we hope the benfits out weigh e.g. by focusing on very key stats and by having automatic reporting.

if (clutter_main_loop_level == 0)
profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git

* Allows the application to replace the standard method that

* The functions must provide at least same locking functionality

*
* As an example, consider an application that has its own recursive
* lock that when held, holds the Clutter lock as well. When Clutter
* unlocks the Clutter lock when entering a recursive main loop, the
* application must temporarily release its lock as well.

Lock the main context when modifying the repaint functions list The repaint functions list can (and should) be manipulated from different threads, but it currently doesn't prevent multiple threads from accessing it concurrently. We should have a simple lock and take it when adding and removing elements from the list; the invocation is still performed under the Big Clutter Lock™, so it doesn't require special handling.

Allow checking initialization without side-effects The _clutter_context_get_default() function will automatically create the main Clutter context; if we just want to check whether Clutter has been initialized this will complicate matters, by requiring a call to g_type_init() inside the client code. Instead, we should simply provide an internal API that checks whether the main Clutter context exists and if it has been initialized, without any side effect.

Implement multi-backend support The Clutter backend split is opaque enough that should allow us to just build all possible backends inside the same shared object, and select the wanted backend at initialization time. This requires some work in the build system, as well as the initialization code, to remove duplicate functions that might cause conflicts at build and link time. We also need to defer all the checks of the internal state of the platform-specific API to run-time type checks.

clutter: Prefer the X11 backend to the Wayland one If clutter is built with both X11 and Wayland support, prefer the (more complete for now) X11 backend. This matches GTK+'s current ordering. This allows distributions to ship a clutter version with both backends built, and using an envvar to switch to the wayland backend and test applications. In the future, applications would be able to choose which backend they prefer and in which order. https://bugzilla.gnome.org/show_bug.cgi?id=695838

Add the ability to set the text direction The direction of the text depends on the locale, and it is the basic setting needed to enable internationalization of user interfaces. This commit allows setting the direction of the PangoContext instance used by Clutter by using the CLUTTER_TEXT_DIRECTION environment variable, or by passing the --clutter-text-direction command line argument. Valid values are: ltr - for left-to-right locales rtl - for right-to-left locales The default is LTR. Ideally, this should be a value set by the localization teams on the PO file, but this step requires some build system surgery to allow the translation of the Clutter strings.

Add error reporting for create_context() failures We kind of assume that stuff will break well before during the ClutterBackend::create_context() implementation if we fail to create a GL context. We do, however, have error reporting in place inside the Backend API to catch those cases. Unfortunately, since we switched to lazy initialization of the Stage, there can be a case of GL context creation failure that still leads to a successful initialization - and a segmentation fault later on. This is clearly Not Good™. Let's try to catch a failure in all the places calling create_context() and report back to the user the error in a meaningful way, before crashing and burning.

Be aware that there are still some issues with this profile option since there are a few special case counters and timers that shouldn't be suspended; noteably the frame counters are incorrect so the per frame stats can't be trusted.

#ifdef CLUTTER_ENABLE_PROFILE
profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git

profiling: Adds initial UProf accounting to Cogl This adds gives Cogl a dedicated UProf context which will be linked together with Clutter's context during clutter_init_real(). Initial timers cover _cogl_journal_flush and _cogl_journal_log_quad You can explicitly ask for a report of Cogl statistics by exporting COGL_PROFILE_OUTPUT_REPORT=1 but since the context is linked with Clutter's the statisitcs will also be shown in the automatic Clutter reports.

Fully integrates CoglMaterial throughout the rest of Cogl This glues CoglMaterial in as the fundamental way that Cogl describes how to fill in geometry. It adds cogl_set_source (), which is used to set the material which will be used by all subsequent drawing functions It adds cogl_set_source_texture as a convenience for setting up a default material with a single texture layer, and cogl_set_source_color is now also a convenience for setting up a material with a solid fill. "drawing functions" include, cogl_rectangle, cogl_texture_rectangle, cogl_texture_multiple_rectangles, cogl_texture_polygon (though the cogl_texture_* funcs have been renamed; see below for details), cogl_path_fill/stroke and cogl_vertex_buffer_draw*. cogl_texture_rectangle, cogl_texture_multiple_rectangles and cogl_texture_polygon no longer take a texture handle; instead the current source material is referenced. The functions have also been renamed to: cogl_rectangle_with_texture_coords, cogl_rectangles_with_texture_coords and cogl_polygon respectivly. Most code that previously did: cogl_texture_rectangle (tex_handle, x, y,...); needs to be changed to now do: cogl_set_source_texture (tex_handle); cogl_rectangle_with_texture_coords (x, y,....); In the less likely case where you were blending your source texture with a color like: cogl_set_source_color4ub (r,g,b,a); /* where r,g,b,a isn't just white */ cogl_texture_rectangle (tex_handle, x, y,...); you will need your own material to do that: mat = cogl_material_new (); cogl_material_set_color4ub (r,g,b,a); cogl_material_set_layer (mat, 0, tex_handle)); cogl_set_source_material (mat); Code that uses the texture coordinates, 0, 0, 1, 1 don't need to use cog_rectangle_with_texure_coords since these are the coordinates that cogl_rectangle will use. For cogl_texture_polygon; as well as dropping the texture handle, the n_vertices and vertices arguments were transposed for consistency. So code previously written as: cogl_texture_polygon (tex_handle, 3, verts, TRUE); need to be written as: cogl_set_source_texture (tex_handle); cogl_polygon (verts, 3, TRUE); All of the unit tests have been updated to now use the material API and test-cogl-material has been renamed to test-cogl-multitexture since any textured quad is now technically a test of CoglMaterial but this test specifically creates a material with multiple texture layers. Note: The GLES backend has not been updated yet; that will be done in a following commit.

Add the ability to set the text direction The direction of the text depends on the locale, and it is the basic setting needed to enable internationalization of user interfaces. This commit allows setting the direction of the PangoContext instance used by Clutter by using the CLUTTER_TEXT_DIRECTION environment variable, or by passing the --clutter-text-direction command line argument. Valid values are: ltr - for left-to-right locales rtl - for right-to-left locales The default is LTR. Ideally, this should be a value set by the localization teams on the PO file, but this step requires some build system surgery to allow the translation of the Clutter strings.

debug: Split debugging notes from behavioural modifiers Some of the ClutterDebugFlags are not meant as a logging facility: they actually change Clutter's behaviour at run-time. It would be useful to have this distinction ratified, and thus split ClutterDebugFlags into two: one DebugFlags for logging facilities and another set of flags for behavioural changes. This split is warranted because: • it should be possible to do "CLUTTER_DEBUG=all" and only have log messages on the output • it should be possible to use behavioural modifiers even on a Clutter that has been compiled without debugging messages support The commit adds two new debugging flags: ClutterPickDebugFlags - controlled by the CLUTTER_PICK environment variable ClutterPaintDebugFlags - controlled by the CLUTTER_PAINT environment variable The PickDebugFlags are: nop-picking dump-pick-buffers While the PaintDebugFlags is: disable-swap-events The mechanism is equivalent to the CLUTTER_DEBUG environment variable, but it does not depend on the debug level selected when configuring and compiling Clutter. The picking and painting debugging flags are initialized at clutter_init() time. http://bugzilla.openedhand.com/show_bug.cgi?id=1991

Bug 1397 - Allow localizing the command line help Clutter has a set of command line options that are added to every application by means of clutter_init() or by obtaining the Clutter GOptionGroup and using g_option_context_parse(). Thus, every Clutter application will automatically have an --help command line switch showing the list of options and their description. At the moment, Clutter does not enable localization of the help, thus making it less than useful on non-English locales. This patch enables the machinery to create a localization file and load it when initializing Clutter, by means of the GLib macros and locale.h API we already use.

* This function does the same work as clutter_init(). Additionally,

* out the help output. Also note that, in case of error, the
* error message will be placed inside @error instead of being
* printed on the display.
*
docs: Document the behaviour in case of init failure Or, better, the fact that the behaviour of any Clutter function will be undefined in case the initialization fails. The value returned by clutter_init() and friends has to be handled properly.

profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git

Add base initialisation function Add a semi-private function, called clutter_base_init(), which initialises the basic Clutter functionalities (at the moment, just the GLib type system) without calling in the backend-specific code. This function is only useful for gtk-doc, to introspect the library when generating documentation for signals, properties and class hierarchy. Also, change the documentation build system to use clutter_base_init() when launching the scanner program.

Clean up crossing event synthesis code Clutter should just require that the windowing system used by a backend adds a device to the stage when the device enters, and removes it from the stage when the device leaves; with this information, we can synthesize every crossing event and update the device state without other intervention from the backend-specific code. The generation of additional crossing events for actors that are covering the stage at the coordinates of the crossing event should be delegated to the event processing code. The x11 and win32 backends need to be modified to relay the enter and leave events from the windowing system.

Clean up grab implementation The grab API is a relic of Clutter 0.6, and hasn't been through proper vetting in a *long* time — mostly due to the fact that we don't really like grabs, and point to the ::captured-event as a way to implement "soft grabs" in toolkits and applications.

event: Unify the off-stage motion events delivery behaviour When we disable the per-actor events delivery Clutter replicates the X11 implicit soft grab for motion events with off-stage. The implicit grab is done whenever the pointer of a device leaves a window with a button still pressed; with the implicit grab in place the window still receives motion events even after the LeaveNotify - until the button is released. The implicit grab is not honoured in the per-actor event deliver case, though, so we have a mismatch between two in theory equivalent cases. Luckily, the fix is pretty trivial: when we check for a motion event with a stage set but without an actor set, and that has off-stage coordinates, we arbitrarily set the source to be the stage of the event and emit the pointer event.

Store the motion event deliver flag in ClutterStage Once upon a time, the land of Clutter had a stage singleton. It was created automatically at initialization time and stayed around even after the main loop was terminated. The singleton was content in being all there was. There also was a global API to handle the configuration of the stage singleton that would affect the behaviour on other classes, signals and properties. Then, an evil wizard came along and locked the stage singleton in his black tower, and twisted it until it was possible to create new stages. These new stages were pesky, and didn't have the same semantics of the singleton: they didn't stay around when closed, or terminate the main loop on delete events. The evil wizard also started moving all the stage-related API from the global context into class-specific methods. Finally, the evil wizard cast a spell, and the stage singleton was demoted to creation on demand - and until somebody called the clutter_stage_get_default() function, the singleton remained in a limbo of NULL pointers and undefined memory areas. There was a last bit - literally - of information still held by the global API; a tiny, little flag that disabled per-actor motion events. The evil wizard added private accessors for it, and stored it inside the stage private structure, in preparation for a deprecation that would come in a future development cycle. The evil wizard looked down upon the land of Clutter from the height of his black tower; the lay of the land had been reshaped into a crucible of potential, and the last dregs of the original force of creation were either molted into new, useful shapes, or blasted away by the sheer fury of his will.

Remove Units from the public API With the recent change to internal floating point values, ClutterUnit has become a redundant type, defined to be a float. All integer entry points are being internally converted to floating point values to be passed to the GL pipeline with the least amount of conversion. ClutterUnit is thus exposed as just a "pixel with fractionary bits", and not -- as users might think -- as generic, resolution and device independent units. not that it was the case, but a definitive amount of people was convinced it did provide this "feature", and was flummoxed about the mere existence of this type. So, having ClutterUnit exposed in the public API doubles the entry points and has the following disadvantages: - we have to maintain twice the amount of entry points in ClutterActor - we still do an integer-to-float implicit conversion - we introduce a weird impedance between pixels and "pixels with fractionary bits" - language bindings will have to choose what to bind, and resort to manually overriding the API + *except* for language bindings based on GObject-Introspection, as they cannot do manual overrides, thus will replicate the entire set of entry points For these reason, we should coalesces every Actor entry point for pixels and for ClutterUnit into a single entry point taking a float, like: void clutter_actor_set_x (ClutterActor *self, gfloat x); void clutter_actor_get_size (ClutterActor *self, gfloat *width, gfloat *height); gfloat clutter_actor_get_height (ClutterActor *self); etc. The issues I have identified are: - we'll have a two cases of compiler warnings: - printf() format of the return values from %d to %f - clutter_actor_get_size() taking floats instead of unsigned ints - we'll have a problem with varargs when passing an integer instead of a floating point value, except on 64bit platforms where the size of a float is the same as the size of an int To be clear: the *intent* of the API should not change -- we still use pixels everywhere -- but: - we remove ambiguity in the API with regard to pixels and units - we remove entry points we get to maintain for the whole 1.0 version of the API - we make things simpler to bind for both manual language bindings and automatic (gobject-introspection based) ones - we have the simplest API possible while still exposing the capabilities of the underlying GL implementation

Move all picking-related operations inside InputDevice The InputDevice objects stores pointer coordinates, state, stage and the actor under the cursor, so if the current backend provides us with one attached to the Event structure then we want the InputDevice itself to update its state and give us the ClutterActor underneath the pointer's cursor.

stage: Move _clutter_do_pick to clutter-stage.c This moves the implementation of _clutter_do_pick to clutter-stage.c and renames it _clutter_stage_do_pick. This function can be compared to _clutter_stage_do_update/redraw in that it prepares for and starts a traversal of a scenegraph descending from a given stage. Since it is desirable that this function should have access to the private state of the stage it is awkward to maintain outside of clutter-stage.c. Besides moving _clutter_do_pick this patch is also able to remove the following private state accessors from clutter-stage-private.h: _clutter_stage_set_pick_buffer_valid, _clutter_stage_get_pick_buffer_valid, _clutter_stage_increment_picks_per_frame_counter, _clutter_stage_reset_picks_per_frame_counter and _clutter_stage_get_picks_per_frame_counter.

event: Unify the off-stage motion events delivery behaviour When we disable the per-actor events delivery Clutter replicates the X11 implicit soft grab for motion events with off-stage. The implicit grab is done whenever the pointer of a device leaves a window with a button still pressed; with the implicit grab in place the window still receives motion events even after the LeaveNotify - until the button is released. The implicit grab is not honoured in the per-actor event deliver case, though, so we have a mismatch between two in theory equivalent cases. Luckily, the fix is pretty trivial: when we check for a motion event with a stage set but without an actor set, and that has off-stage coordinates, we arbitrarily set the source to be the stage of the event and emit the pointer event.

Remove Units from the public API With the recent change to internal floating point values, ClutterUnit has become a redundant type, defined to be a float. All integer entry points are being internally converted to floating point values to be passed to the GL pipeline with the least amount of conversion. ClutterUnit is thus exposed as just a "pixel with fractionary bits", and not -- as users might think -- as generic, resolution and device independent units. not that it was the case, but a definitive amount of people was convinced it did provide this "feature", and was flummoxed about the mere existence of this type. So, having ClutterUnit exposed in the public API doubles the entry points and has the following disadvantages: - we have to maintain twice the amount of entry points in ClutterActor - we still do an integer-to-float implicit conversion - we introduce a weird impedance between pixels and "pixels with fractionary bits" - language bindings will have to choose what to bind, and resort to manually overriding the API + *except* for language bindings based on GObject-Introspection, as they cannot do manual overrides, thus will replicate the entire set of entry points For these reason, we should coalesces every Actor entry point for pixels and for ClutterUnit into a single entry point taking a float, like: void clutter_actor_set_x (ClutterActor *self, gfloat x); void clutter_actor_get_size (ClutterActor *self, gfloat *width, gfloat *height); gfloat clutter_actor_get_height (ClutterActor *self); etc. The issues I have identified are: - we'll have a two cases of compiler warnings: - printf() format of the return values from %d to %f - clutter_actor_get_size() taking floats instead of unsigned ints - we'll have a problem with varargs when passing an integer instead of a floating point value, except on 64bit platforms where the size of a float is the same as the size of an int To be clear: the *intent* of the API should not change -- we still use pixels everywhere -- but: - we remove ambiguity in the API with regard to pixels and units - we remove entry points we get to maintain for the whole 1.0 version of the API - we make things simpler to bind for both manual language bindings and automatic (gobject-introspection based) ones - we have the simplest API possible while still exposing the capabilities of the underlying GL implementation

Clean up crossing event synthesis code Clutter should just require that the windowing system used by a backend adds a device to the stage when the device enters, and removes it from the stage when the device leaves; with this information, we can synthesize every crossing event and update the device state without other intervention from the backend-specific code. The generation of additional crossing events for actors that are covering the stage at the coordinates of the crossing event should be delegated to the event processing code. The x11 and win32 backends need to be modified to relay the enter and leave events from the windowing system.

Make the pick id pool per Stage The id pool used for the actor's id should be a per-stage field. At some point, we might have a Stage mapped to multiple framebuffers, or each Stage mapped to a different framebuffer; also, on backend with low color precision we don't want to exhaust the size of the available ids with a global pool. Finally, it's yet another thing we can remove from the global Clutter context. Having the id pool allocated per-stage, and the pick id assigned on Actor:mapped will make the whole pick-id more reliable and future proof. http://bugzilla.clutter-project.org/show_bug.cgi?id=2633 https://bugzilla.gnome.org/show_bug.cgi?id=647876

Bug 1397 - Allow localizing the command line help Clutter has a set of command line options that are added to every application by means of clutter_init() or by obtaining the Clutter GOptionGroup and using g_option_context_parse(). Thus, every Clutter application will automatically have an --help command line switch showing the list of options and their description. At the moment, Clutter does not enable localization of the help, thus making it less than useful on non-English locales. This patch enables the machinery to create a localization file and load it when initializing Clutter, by means of the GLib macros and locale.h API we already use.

2007-10-16 Emmanuele Bassi <ebassi@openedhand.com> * clutter/clutter-timeline.[ch]: Added ClutterTimeline:duration, a property for setting the duration of a timeline in milliseconds. The property comes with accessors and a new constructor. The frame rate used is the default value. * clutter/clutter-private.h: * clutter/clutter-main.[ch]: Add clutter_get_default_frame_rate() and clutter_set_default_frame_rate(); these two functions control the default frame rate to be used when creating timelines. Currently is set to 60 frames-per-second.

Clean up grab implementation The grab API is a relic of Clutter 0.6, and hasn't been through proper vetting in a *long* time — mostly due to the fact that we don't really like grabs, and point to the ::captured-event as a way to implement "soft grabs" in toolkits and applications. The implementation of full and device grabs uses weak references on actors instead of using the ::destroy signal, which is meant exactly for the case of releasing pointers to actors when they are disposed. The API naming scheme is also fairly broken, especially for device-related grabs. Finally, keyboard device grabs are just not implemented. We can, in one go, clean up this mess and deprecate a bunch of badly named API by introducing generic device grab/ungrab methods on ClutterInputDevice, and re-implement the current API on top of them.

We can, in one go, clean up this mess and deprecate a bunch of badly named API by introducing generic device grab/ungrab methods on ClutterInputDevice, and re-implement the current API on top of them.

[docs] Note that grabs are evil Grabs are an entirely evil way to override the whole event delivery machinery that Clutter has in place. A pointer grab can be effectively replaced by a much more reliable ::captured-event signal handler, for instance. Sometimes, grabs are a necessary evil -- and that is why Clutter exposes them in the API; that should not fool anyone into thinking that they should be used unless strictly necessary.

Clean up grab implementation The grab API is a relic of Clutter 0.6, and hasn't been through proper vetting in a *long* time — mostly due to the fact that we don't really like grabs, and point to the ::captured-event as a way to implement "soft grabs" in toolkits and applications. The implementation of full and device grabs uses weak references on actors instead of using the ::destroy signal, which is meant exactly for the case of releasing pointers to actors when they are disposed. The API naming scheme is also fairly broken, especially for device-related grabs. Finally, keyboard device grabs are just not implemented. We can, in one go, clean up this mess and deprecate a bunch of badly named API by introducing generic device grab/ungrab methods on ClutterInputDevice, and re-implement the current API on top of them.

Replace clutter_set_use_mipmapped_text with clutter_set_font_flags The hope is that this function makes it easier to extend the font settings with more flags without having to add a function for every setting. A new flag for enabling hinting has been added. If set, this changes the font options on the global PangoContext and any newly created PangoContexts. The options are only set if the flag is changed from the default so it won't override any detailed setting chosen by the backend.

2008-05-28 Emmanuele Bassi <ebassi@openedhand.com> Bug #919 - Replacement pango renderer (Neil Roberts) * clutter/clutter-backend.h: * clutter/clutter-backend.c: (clutter_backend_set_font_options), (clutter_backend_get_font_options): Add the ability to set the cairo_font_options_t* for the backend at construction time, so that backend implementations can have their own options. * clutter/clutter-color.c: Include pango/pango-attributes.h for the pango_color_parse() function. * clutter/clutter-label.c: (clutter_label_ensure_layout), (clutter_label_init), (clutter_label_set_text), (clutter_label_set_font_name), (clutter_label_set_ellipsize), (clutter_label_set_use_markup): Ensure that the cache is always primed when the Label changes; this makes sure that the cache is rebuilt outside the paint run, which should make the painting perform better especially on embedded devices. * clutter/clutter-entry.c: (clutter_entry_ensure_layout), (clutter_entry_init), (clutter_entry_set_text), (clutter_entry_set_font_name): Ditto as above. * clutter/clutter-private.h: * clutter/clutter-main.[ch]: Create the font-map inside the main context; add two new functions: clutter_clear_glyph_cache() clutter_set_use_mipmapped_text() that control the glyphs cache. * clutter/pango/Makefile.am: * clutter/pango/pangoclutter-fontmap.c: * clutter/pango/pangoclutter-private.h: * clutter/pango/pangoclutter-render.c: * clutter/pango/pangoclutter.h: Rewrite the Pango renderer using a PangoCairo context and saving the glyphs inside a more efficient cache. * configure.ac: Depend on pangocairo instead of pangoft2.

Add repaint functions Sometimes it is necessary for third party code to have a function called during the redraw process, so that you can update the scenegraph before it is painted.

Improve repaint functions It is sometimes useful to be able to have better control on when a repaint function is called. Currently, all repaint functions are called prior to the stages update phase of the frame processing. We can introduce flags to represent the point in the frame update process in which we wish Clutter called the repaint function. As a bonus, we can also add a flag that causes adding a repaint function to spin the master clock.

Avoid direct access to the main context events queue The GQueue that stores the global events queue is handled all over the place: • the structure is created in _clutter_backend_init_events(); • the queue is handled in clutter-event.c, clutter-stage.c and clutter-backend.c; • ClutterStage::dispose cleans up the events associated with the stage being destroyed; • the queue is destroyed in ClutterBackend::dispose. Since we need to have access to it in different places we cannot put it inside ClutterBackendPrivate, hence it should stay in ClutterMainContext; but we should still manage it from just one place - preferably by the ClutterEvent API only.

Avoid direct access to the main context events queue The GQueue that stores the global events queue is handled all over the place: • the structure is created in _clutter_backend_init_events(); • the queue is handled in clutter-event.c, clutter-stage.c and clutter-backend.c; • ClutterStage::dispose cleans up the events associated with the stage being destroyed; • the queue is destroyed in ClutterBackend::dispose. Since we need to have access to it in different places we cannot put it inside ClutterBackendPrivate, hence it should stay in ClutterMainContext; but we should still manage it from just one place - preferably by the ClutterEvent API only.

stage: Maintain the motion event delivery invariants It is possible, by calling clutter_set_motion_events_enabled() prior to the creation of any stage, to control the per-actor motion event delivery flag on each newly created stage. Since we deprecated the global accessor functions in favour of the per-Stage ones, we need to remove the call to clutter_get_motion_events_enabled() inside the ClutterStage instance initialization, and replace it with an internal function. This code will go away when we can finally break API and remove the deprecated functions.

Allow checking the backend type at run-time Portable code should be allowed to check type backend currently being used, so that it can use platform-specific API (not just Clutter's). We don't want to go down the GDK route, with public types for ClutterBackend and ClutterStageWindow implementations, and use the type system, e.g.: #ifdef GDK_WINDOWING_X11 if (GDK_IS_WINDOW_X11 (window)) use_x11_api (window); else #endif #ifdef GDK_WINDOWING_WIN32 if (GDK_IS_WINDOW_WIN32 (window)) use_win32_api (window); else #endif g_critical ("Unsupported backend"); This system would make us expose the backend system, and we want to still reserve us the option to change the backend system to increase its granularity — e.g. choosing different input event systems regardless of the windowing system. This commit adds a simple function that checks the backend type against a symbolic constant — the same constant string that can be used to select the backend at run-time through the CLUTTER_BACKEND environment variable.

debug: Group debug messages by timestamps Instead of showing the full timestamp for debugging messages that happen within a second, showing the delta from the previous full timestamp can be more useful when debugging; this allows immediately seeing the time difference, instead of doing the math in our heads.

Rework debug output Make it consistent across the various build options (with or without profiling enabled), and add a timestamp using the monotonic clock to every debug message.

debug: Clean up profile/debug symbols Since we have a _clutter_debug_message() function compiled in unconditionally we have no further need for the equivalent conditional version defined in clutter-profile.[ch]: we can simply do the work in one function.

Fix building with profiling enabled There was an #ifdef'd section of code for profiling that was using the wrong variable name so it would not build. Reviewed-by: Emmanuele Bassi <ebassi@linux.intel.com>

Add diagnostic mode GLib has a "diagnostic mode" switch that can be checked to enable debug messages on deprecated properties and signals, as these are purely run-time constructs, and as such cannot be caught by compiler warnings. The diagnostic mode is toggled by a simple environment variable, and can be used to ease porting of application code. We can use something similar to mark deprecated virtual functions and other run-time constructs; to avoid collisions, we should use our own environment variable, CLUTTER_ENABLE_DIAGNOSTIC.
