Adds an example cogl wayland compositor This adds an example cogl compositor to test the _cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4 output displays but doesn't support input since Cogl doesn't deal with input. It's quite a minimal example of what it takes to write a wayland compositor so could be interesting to anyone learning about wayland.

Create standalone public wayland client/server headers Because the wayland-client-protocol.h header defines symbols that collide with the wayland-server-protocol.h header we allow applications to explicitly ensure that they are only including one at a time by exposing corresponding <cogl/cogl-wayland-client.h> and <cogl/cogl-wayland-server.h> headers. This also adds a missing guard to cogl-texture-2d.h that it isn't included directly. Reviewed-by: Neil Roberts <neil@linux.intel.com>

cogland: Add an option to split the desktop into four outputs Previously Cogland would always split the desktop into four outputs. Although this is quite neat to demonstrate that it's possible, it's quite annoying in practice while testing. This patch turns it into a command line option which defaults to off.

cogland: Update to the Wayland 1.0 API This updates Cogland example compositor to use the stable Wayland 1.0 API. • When the client attaches a new buffer to a surface it is now added to a struct contaning pending the state instead of immediately switching to the new buffer. This state is then flushed when the surface is committed. • The frame callbacks are now queued in a pending list and only added to the compositor's main list when the surface is committed. Both lists are now a wl_list instead of a GQueue because it makes it easier to remove the callback without knowing which list it is in. • When the buffer is destroyed for a surface the resource for the buffer is now sent a release event. • It now flushes the clients in the prepare for the for the Wayland event GSource. This is part of the multi-threaded API in this Wayland patch: http://cgit.freedesktop.org/wayland/wayland/commit/?id=53d24713a31d59 • Implements a dummy wl_region interface. The only interfaces that actually use regions (the opaque and input regions) are ignored but we need the interface to create a resource. • Most the of the SHM interface is now implemented directly in libwayland-server except that it still needs to copy the data to the subregion of the texture when the damage region is committed. • The callback list for when a resource is destroyed has been unified into a generic wl_signal implementation so the signature for the functions has been changed. http://cgit.freedesktop.org/wayland/wayland/commit/?h=6802eaa68af9022 • The wl_buffer struct no longer has a user_data parameter so we can't attach our own CoglandBuffer data to it. Instead the CoglandSurface now just keeps track of the wl_buffer directly. • The Cogland example is now unconditionally built instead of checking the Wayland version number in the configure script. It looks like this check was broken anyway because it was checking the version of the gbm package rather than a Wayland package.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

This state is then flushed when the surface is committed. • The frame callbacks are now queued in a pending list and only added to the compositor's main list when the surface is committed.

This is part of the multi-threaded API in this Wayland patch: http://cgit.freedesktop.org/wayland/wayland/commit/?id=53d24713a31d59 • Implements a dummy wl_region interface. The only interfaces that actually use regions (the opaque and input regions) are ignored but we need the interface to create a resource. • Most the of the SHM interface is now implemented directly in libwayland-server except that it still needs to copy the data to the subregion of the texture when the damage region is committed. • The callback list for when a resource is destroyed has been unified into a generic wl_signal implementation so the signature for the functions has been changed. http://cgit.freedesktop.org/wayland/wayland/commit/?h=6802eaa68af9022 • The wl_buffer struct no longer has a user_data parameter so we can't attach our own CoglandBuffer data to it. Instead the CoglandSurface now just keeps track of the wl_buffer directly. • The Cogland example is now unconditionally built instead of checking the Wayland version number in the configure script.

framebuffer: Add cogl_framebuffer draw methods This adds cogl_framebuffer_ apis for drawing attributes and primitives that replace corresponding apis that depend on the default CoglContext. This is part of the on going effort to adapt the Cogl api so it no longer depends on a global context variable. All the new drawing functions also take an explicit pipeline argument since we are also aiming to avoid being a stateful api like Cairo and OpenGL. Being stateless makes it easier for orthogonal components to share access to the GPU. Being stateless should also minimize any impedance miss-match for those wanting to build higher level stateless apis on top of Cogl. Note: none of the legacy, global state options such as cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or cogl_program_use() are supported by these new drawing apis and if set will simply be silently ignored.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

cogland: Update to the Wayland 1.0 API This updates Cogland example compositor to use the stable Wayland 1.0 API. • When the client attaches a new buffer to a surface it is now added to a struct contaning pending the state instead of immediately switching to the new buffer. This state is then flushed when the surface is committed. • The frame callbacks are now queued in a pending list and only added to the compositor's main list when the surface is committed. Both lists are now a wl_list instead of a GQueue because it makes it easier to remove the callback without knowing which list it is in. • When the buffer is destroyed for a surface the resource for the buffer is now sent a release event. • It now flushes the clients in the prepare for the for the Wayland event GSource. This is part of the multi-threaded API in this Wayland patch: http://cgit.freedesktop.org/wayland/wayland/commit/?id=53d24713a31d59 • Implements a dummy wl_region interface. The only interfaces that actually use regions (the opaque and input regions) are ignored but we need the interface to create a resource. • Most the of the SHM interface is now implemented directly in libwayland-server except that it still needs to copy the data to the subregion of the texture when the damage region is committed. • The callback list for when a resource is destroyed has been unified into a generic wl_signal implementation so the signature for the functions has been changed. http://cgit.freedesktop.org/wayland/wayland/commit/?h=6802eaa68af9022 • The wl_buffer struct no longer has a user_data parameter so we can't attach our own CoglandBuffer data to it. Instead the CoglandSurface now just keeps track of the wl_buffer directly. • The Cogland example is now unconditionally built instead of checking the Wayland version number in the configure script.

Add -Wmissing-declarations to maintainer flags and fix problems This option to GCC makes it give a warning whenever a global function is defined without a declaration. This should catch cases were we've defined a function but forgot to put it in a header. In that case it is either only used within one file so we should make it static or we should declare it in a header. The following changes where made to fix problems: • Some functions were made static • cogl-path.h (the one containing the 1.0 API) was split into two files, one defining the functions and one defining the enums so that cogl-path.c can include the enum and function declarations from the 2.0 API as well as the function declarations from the 1.0 API. • cogl2-clip-state has been removed. This only had one experimental function called cogl_clip_push_from_path but as this is unstable we might as well remove it favour of the equivalent cogl_framebuffer_* API. • The GLX, SDL and WGL winsys's now have a private header to define their get_vtable function instead of directly declaring in the C file where it is called. • All places that were calling COGL_OBJECT_DEFINE need to have the cogl_is_whatever function declared so these have been added either as a public function or in a private header. • Some files that were not including the header containing their function declarations have been fixed to do so. • Any unused error quark functions have been removed. If we later want them we should add them back one by one and add a declaration for them in a header. • _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and made a public function with a declaration in cogl-framebuffer.h • Similarly for CoglOnscreen. • cogl_vdraw_indexed_attributes is called cogl_framebuffer_vdraw_indexed_attributes in the header. The definition has been changed to match the header. • cogl_index_buffer_allocate has been removed. This had no declaration and I'm not sure what it's supposed to do. • CoglJournal has been changed to use the internal CoglObject macro so that it won't define an exported cogl_is_journal symbol. • The _cogl_blah_pointer_from_handle functions have been removed. CoglHandle isn't used much anymore anyway and in the few places where it is used I think it's safe to just use the implicit cast from void* to the right type. • The test-utils.h header for the conformance tests explicitly disables the -Wmissing-declaration option using a pragma because all of the tests declare their main function without a header. Any mistakes relating to missing declarations aren't really important for the tests. • cogl_quaternion_init_from_quaternion and init_from_matrix have been given declarations in cogl-quaternion.h Reviewed-by: Robert Bragg <robert@linux.intel.com>

wayland-server: Update because wl_shm_buffer is no longer a wl_buffer The Wayland server API has changed so that wl_shm_buffer is no longer a type of wl_buffer and it instead must be retrieved directly from the resource. cogl_wayland_texture_2d_new_from_buffer now takes a resource pointer instead of directly taking a wl_buffer and it will do different things depending on whether it can get a wl_shm_buffer out of the resource instead of trying to query the buffer type. Cogland has also been updated so that it tracks a resource for buffers of surfaces instead of directly tracking a wl_buffer. This are pointed to by a new CoglandBuffer struct which can be referenced by a CoglandBufferReference. The WL_BUFFER_RELEASE event will be posted when the last reference to the buffer is removed instead of directly whenever a new buffer is attached. This is similar to how Weston works. https://bugzilla.gnome.org/show_bug.cgi?id=702999 Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 9b35e1651ad0e46ed489893b60563e2c25457701) Conflicts: examples/cogland.c

Add _primitive_draw to replace _framebuffer_draw_primitive When splitting out the CoglPath api we saw that we would be left with inconsistent drawing apis if the drawing apis in core Cogl were lumped into the cogl_framebuffer_ api considering other Cogl sub-libraries or that others will want to create higher level drawing apis outside of Cogl but can't use the same namespace. So that we can aim for a more consistent style this adds a cogl_primitive_draw() api, comparable to cogl_path_fill() or cogl_pango_show_layout() that's intended to replace cogl_framebuffer_draw_primitive() Note: the attribute and rectangle drawing apis are still in the cogl_framebuffer_ namespace and this might potentially change but in these cases there is no single object representing the thing being drawn so it seems a more reasonable they they live in the framebuffer namespace for now. Note: the cogl_framebuffer_draw_primitive() api isn't removed by this patch so it can more conveniently be cherry picked to the 1.16 branch so we can mark it deprecated for a short while. Even though it's marked as experimental api we know that there are people using the api so we'd like to give them a chance to switch to the new api.

cogland: Handle damage events for non-shm buffers too When a Wayland compositor gets a commit it only needs to redraw the region specified by the pending damage event. Previously Cogland was ignoring damage events for non-shm buffers and just always queuing a redraw after a commit event. This patch changes it to queue a redraw only in response to a damage event. In practice this doesn't really make much difference because Cogland doesn't do anything clever to handle updating a sub-region of the screen, but it more costly matches the model a compositor should use.

Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

cogland: Update to the Wayland 1.0 API This updates Cogland example compositor to use the stable Wayland 1.0 API. • When the client attaches a new buffer to a surface it is now added to a struct contaning pending the state instead of immediately switching to the new buffer. This state is then flushed when the surface is committed. • The frame callbacks are now queued in a pending list and only added to the compositor's main list when the surface is committed. Both lists are now a wl_list instead of a GQueue because it makes it easier to remove the callback without knowing which list it is in. • When the buffer is destroyed for a surface the resource for the buffer is now sent a release event. • It now flushes the clients in the prepare for the for the Wayland event GSource. This is part of the multi-threaded API in this Wayland patch: http://cgit.freedesktop.org/wayland/wayland/commit/?id=53d24713a31d59 • Implements a dummy wl_region interface. The only interfaces that actually use regions (the opaque and input regions) are ignored but we need the interface to create a resource. • Most the of the SHM interface is now implemented directly in libwayland-server except that it still needs to copy the data to the subregion of the texture when the damage region is committed. • The callback list for when a resource is destroyed has been unified into a generic wl_signal implementation so the signature for the functions has been changed. http://cgit.freedesktop.org/wayland/wayland/commit/?h=6802eaa68af9022 • The wl_buffer struct no longer has a user_data parameter so we can't attach our own CoglandBuffer data to it. Instead the CoglandSurface now just keeps track of the wl_buffer directly. • The Cogland example is now unconditionally built instead of checking the Wayland version number in the configure script.

Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h

cogland: Handle damage events for non-shm buffers too When a Wayland compositor gets a commit it only needs to redraw the region specified by the pending damage event. Previously Cogland was ignoring damage events for non-shm buffers and just always queuing a redraw after a commit event. This patch changes it to queue a redraw only in response to a damage event. In practice this doesn't really make much difference because Cogland doesn't do anything clever to handle updating a sub-region of the screen, but it more costly matches the model a compositor should use.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Adds CoglError api Although we use GLib internally in Cogl we would rather not leak GLib api through Cogl's own api, except through explicitly namespaced cogl_glib_ / cogl_gtype_ feature apis. One of the benefits we see to not leaking GLib through Cogl's public API is that documentation for Cogl won't need to first introduce the Glib API to newcomers, thus hopefully lowering the barrier to learning Cogl. This patch provides a Cogl specific typedef for reporting runtime errors which by no coincidence matches the typedef for GError exactly. If Cogl is built with --enable-glib (default) then developers can even safely assume that a CoglError is a GError under the hood. This patch also enforces a consistent policy for when NULL is passed as an error argument and an error is thrown. In this case we log the error and abort the application, instead of silently ignoring it. In common cases where nothing has been implemented to handle a particular error and/or where applications are just printing the error and aborting themselves then this saves some typing. This also seems more consistent with language based exceptions which usually cause a program to abort if they are not explicitly caught (which passing a non-NULL error signifies in this case) Since this policy for NULL error pointers is stricter than the standard GError convention, there is a clear note in the documentation to warn developers that are used to using the GError api. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit b068d5ea09ab32c37e8c965fc8582c85d1b2db46) Note: Since we can't change the Cogl 1.x api the patch was changed to not rename _error_quark() functions to be _error_domain() functions and although it's a bit ugly, instead of providing our own CoglError type that's compatible with GError we simply #define CoglError to GError unless Cogl is built with glib disabled. Note: this patch does technically introduce an API break since it drops the cogl_error_get_type() symbol generated by glib-mkenum (Since the CoglError enum was replaced by a CoglSystemError enum) but for now we are assuming that this will not affect anyone currently using the Cogl API. If this does turn out to be a problem in practice then we would be able to fix this my manually copying an implementation of cogl_error_get_type() generated by glib-mkenum into a compatibility source file and we could also define the original COGL_ERROR_ enums for compatibility too. Note: another minor concern with cherry-picking this patch to the 1.14 branch is that an api scanner would be lead to believe that some APIs have changed, and for example the gobject-introspection parser which understands the semantics of GError will not understand the semantics of CoglError. We expect most people that have tried to use gobject-introspection with Cogl already understand though that it is not well suited to generating bindings of the Cogl api anyway and we aren't aware or anyone depending on such bindings for apis involving GErrors. (GnomeShell only makes very-very minimal use of Cogl via the gjs bindings for the cogl_rectangle and cogl_color apis.) The main reason we have cherry-picked this patch to the 1.14 branch even given the above concerns is that without it it would become very awkward for us to cherry-pick other beneficial patches from master.

Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h

Add compiler deprecation warnings This adds compiler symbol deprecation declarations for old Cogl APIs so that users can easily see via compiler warning when they are using these symbols, and also see a hint for what the apis should be replaced with. So that users of Cogl can manage when to show these warnings this introduces a scheme borrowed from glib whereby you can declare what version of the Cogl api you are using: COGL_VERSION_MIN_REQUIRED can be defined to indicate the oldest Cogl api that the application wants to use. Cogl will only warn about deprecations for symbols that were deprecated earlier than this required version. If this is left undefined then by default Cogl will warn about all deprecations. COGL_VERSION_MAX_ALLOWED can be defined to indicate the newest api that the application uses. If the application uses symbols newer than this then Cogl will give a warning about that. This patch removes the need to maintain the COGL_DISABLE_DEPRECATED guards around deprecated symbols. This patch fixes a few uses of deprecated symbols in the examples/ Reviewed-by: Neil Roberts <neil@linux.intel.com>

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Adds CoglError api Although we use GLib internally in Cogl we would rather not leak GLib api through Cogl's own api, except through explicitly namespaced cogl_glib_ / cogl_gtype_ feature apis. One of the benefits we see to not leaking GLib through Cogl's public API is that documentation for Cogl won't need to first introduce the Glib API to newcomers, thus hopefully lowering the barrier to learning Cogl. This patch provides a Cogl specific typedef for reporting runtime errors which by no coincidence matches the typedef for GError exactly. If Cogl is built with --enable-glib (default) then developers can even safely assume that a CoglError is a GError under the hood. This patch also enforces a consistent policy for when NULL is passed as an error argument and an error is thrown. In this case we log the error and abort the application, instead of silently ignoring it. In common cases where nothing has been implemented to handle a particular error and/or where applications are just printing the error and aborting themselves then this saves some typing. This also seems more consistent with language based exceptions which usually cause a program to abort if they are not explicitly caught (which passing a non-NULL error signifies in this case) Since this policy for NULL error pointers is stricter than the standard GError convention, there is a clear note in the documentation to warn developers that are used to using the GError api. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit b068d5ea09ab32c37e8c965fc8582c85d1b2db46) Note: Since we can't change the Cogl 1.x api the patch was changed to not rename _error_quark() functions to be _error_domain() functions and although it's a bit ugly, instead of providing our own CoglError type that's compatible with GError we simply #define CoglError to GError unless Cogl is built with glib disabled. Note: this patch does technically introduce an API break since it drops the cogl_error_get_type() symbol generated by glib-mkenum (Since the CoglError enum was replaced by a CoglSystemError enum) but for now we are assuming that this will not affect anyone currently using the Cogl API. If this does turn out to be a problem in practice then we would be able to fix this my manually copying an implementation of cogl_error_get_type() generated by glib-mkenum into a compatibility source file and we could also define the original COGL_ERROR_ enums for compatibility too. Note: another minor concern with cherry-picking this patch to the 1.14 branch is that an api scanner would be lead to believe that some APIs have changed, and for example the gobject-introspection parser which understands the semantics of GError will not understand the semantics of CoglError. We expect most people that have tried to use gobject-introspection with Cogl already understand though that it is not well suited to generating bindings of the Cogl api anyway and we aren't aware or anyone depending on such bindings for apis involving GErrors. (GnomeShell only makes very-very minimal use of Cogl via the gjs bindings for the cogl_rectangle and cogl_color apis.) The main reason we have cherry-picked this patch to the 1.14 branch even given the above concerns is that without it it would become very awkward for us to cherry-pick other beneficial patches from master.

Update all of the examples to use cogl_poll_get_info The aim is that it should be a requirement that all Cogl applications hook their mainloops into Cogl so we should lead by examples. Most of the examples now just call cogl_poll_get_info and then g_poll with a zero timeout so that they can continue to constantly redraw. The SDL example is a bit special because SDL makes it very difficult to wait on either a timeout or any file descriptors. The SDL winsys is documented not to require blocking on any file descriptors so we can ignore that. It implements the timeout by adding an SDL timer which pushes an event to the queue to wake up SDL_GetEvent. The Cogland example was already using the glib main loop so that one has been updated to add the CoglGLibSource to it. Reviewed-by: Robert Bragg <robert@linux.intel.com>

Adds an example cogl wayland compositor This adds an example cogl compositor to test the _cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4 output displays but doesn't support input since Cogl doesn't deal with input. It's quite a minimal example of what it takes to write a wayland compositor so could be interesting to anyone learning about wayland.

cogland: Update to the Wayland 1.0 API This updates Cogland example compositor to use the stable Wayland 1.0 API. • When the client attaches a new buffer to a surface it is now added to a struct contaning pending the state instead of immediately switching to the new buffer. This state is then flushed when the surface is committed. • The frame callbacks are now queued in a pending list and only added to the compositor's main list when the surface is committed. Both lists are now a wl_list instead of a GQueue because it makes it easier to remove the callback without knowing which list it is in. • When the buffer is destroyed for a surface the resource for the buffer is now sent a release event. • It now flushes the clients in the prepare for the for the Wayland event GSource. This is part of the multi-threaded API in this Wayland patch: http://cgit.freedesktop.org/wayland/wayland/commit/?id=53d24713a31d59 • Implements a dummy wl_region interface. The only interfaces that actually use regions (the opaque and input regions) are ignored but we need the interface to create a resource. • Most the of the SHM interface is now implemented directly in libwayland-server except that it still needs to copy the data to the subregion of the texture when the damage region is committed. • The callback list for when a resource is destroyed has been unified into a generic wl_signal implementation so the signature for the functions has been changed. http://cgit.freedesktop.org/wayland/wayland/commit/?h=6802eaa68af9022 • The wl_buffer struct no longer has a user_data parameter so we can't attach our own CoglandBuffer data to it. Instead the CoglandSurface now just keeps track of the wl_buffer directly. • The Cogland example is now unconditionally built instead of checking the Wayland version number in the configure script. It looks like this check was broken anyway because it was checking the version of the gbm package rather than a Wayland package.

cogland: Try forcing an EGL context Cogland works a lot better with an EGL context because then Mesa will automatically set up the wl_drm object and it can accept DRM buffers. However Cogland is still useful with GLX because it can gracefully fallback to accepting only SHM buffers. This patch therefore makes it first try creating and connecting a renderer with the EGL constraint, but if that doesn't work it will try again without it.

Update all of the examples to use cogl_poll_get_info The aim is that it should be a requirement that all Cogl applications hook their mainloops into Cogl so we should lead by examples. Most of the examples now just call cogl_poll_get_info and then g_poll with a zero timeout so that they can continue to constantly redraw. The SDL example is a bit special because SDL makes it very difficult to wait on either a timeout or any file descriptors. The SDL winsys is documented not to require blocking on any file descriptors so we can ignore that. It implements the timeout by adding an SDL timer which pushes an event to the queue to wake up SDL_GetEvent. The Cogland example was already using the glib main loop so that one has been updated to add the CoglGLibSource to it. Reviewed-by: Robert Bragg <robert@linux.intel.com>
