In _cogl_material_pre_change_notify we need to identify if it's a sparse
property being changed and if so initialize the state group if the given
material isn't currently the authority for it.
Previously we were unconditionally calling
_cogl_material_initialize_state which would e.g. NULL the layer
differences list of a material each time a layer change was notified.
It would also call _cogl_material_initialize_state for non-sparse
properties which should always be valid at this point so the function
has been renamed to _cogl_material_initialize_sparse_state to make this
clearer with a corresponding g_return_if_fail check.
This fixes how we copy layer differences in
_cogl_material_copy_layer_differences.
We were making a redundant g_list_copy of the src differences and then
iterating the src list calling _cogl_material_add_layer_difference for
each entry which would double the list length, but the initial copy
directly referenced the original layers which wasn't correct.
Also we were initializing dest->n_layers before copying the layer
differences but the act of copying the differences will re-initialize
n_layers to 0 when adding the first layer_difference since it will
trigger a layer_pre_change_notify and since the dest material isn't yet
a STATE_LAYERS authority the state group is initialized before allowing
the change.
In _cogl_material_texture_storage_change_notify we were potentially
dereferencing layer->texture without checking first that it is the
authority of texture state. We now use
_cogl_material_layer_get_texture() instead.
This improve the dot file output available when calling
_cogl_debug_dump_materials_dot_file. The material graph now directly
points into the layer graph and the layers now show the texture unit
index.
DRM is available on more platforms than Linux (e.g. kFreeBSD), but
Clutter currently FTBFS there because of not being an alternative to
the __linux__ code (where it should be HAVE_DRM).
Instead of copying the DRM data structures, we should use libdrm when
falling back to directly requesting to wait for the vblank.

When setting :use-markup we always pass the contents of the Text actor
to clutter_text_set_markup_internal(); if string contains any markup,
this ends up being parsed and used - even when :use-markup is set to
FALSE.

When the texture is set on a layer so that it is back to the parent's
texture it would clear the texture change flag but it wouldn't unref
the texture. The free function for a material layer does not unref the
texture if the change flag is cleared so the texture would end up
leaking. This happens for ClutterTexture because it disposes the
texture by setting layer 0 of the material to COGL_INVALID_HANDLE
which ends up the same as the default material.
It's a XSL FAQ to be able to chomp text nodes and we just have to copy
and paste a XSLT 1.0 solution from:
http://dpawson.co.uk/xsl/sect2/N8321.html#d11325e833
Let's then empower our cookbook customization layer to chomp text nodes,
children of programlisting.
The generated cookbook files (either HTML or PDF) do not only depend on
clutter-cookbok.xml but also on all the chapters that compose the
cookbook. Add this dependency to the Makefile rules to have make rebuild
the book when a chapter changes.
Since XML_FILES is now the list of source files, move recipe-template.xml
to EXTRA_DIST.
In _cogl_material_layer_pre_paint we were mistakenly dereferencing the
layer->texture member for the passed layer instead of dereferencing the
texture state authority which was causing crashes in some cases.
LayoutMeta instances are created lazily. If an actor is added to a
container with a layout manager then the first time the layout manager
might be creating the LayoutMeta instance could be during the allocation
cycle caused by calling clutter_actor_show(). When a LayoutMeta is
instantiated for the first time, a list of properties can be set - and
this might lead to the emission of the ::layout-changed signal. The
signal is, most typically, going to cause a relayout to be queued, and a
warning will be printed on the terminal.
We should freeze the emission of the ::layout-changed signal during the
creation of the LayoutMeta instances, and thaw it after that.
If a Texture has been set to:
• keep its size synchronized with the image data
• maintain the aspect ratio of the image data
then it should also change its request mode depending on the orientation
of the image data, so that layout managers have a fighting chance of
sizing it correctly.
Added initialization of minimum window size property on Cocoa
side. This property works when user change window size by mouse
dragging. But when size is changed by clutter_actor_set_size this
property will not help and was added another check in
clutter_stage_osx_resize. Also osx_get_geometry was refactoried
because it returns incorrect values in many cases but now size is
saved in [Window reshape] in requisition_width/height and this value
will be returned in any case to frontend.
It's important step of initialization because all features calls from
font rendering libs based on this parameter. By default it equals to
-1 and test-text-cache test crashes in this case.
Trick with hiding view while showing the stage affects on responder
chain. The main view ceases to be first responder and we should
manually set first responder.
Problem was in incorrect application initialization.
[NSApplication sharedApplication] should be call in backend init(not
in init stage). It doesn't require any data and only makes a
connection to window server.
Cleanup clutter_backend_osx_post_parse function and move context
initialization to clutter_backend_osx_create_context. The OpenGL pixel
format attributes were taken as is. Also move bringing application to
foreground in clutter_stage_osx_realize, it seems there is best place
for it.
Viewport didn't initialized before OGL drawing and it causes crash on
assert so added viewport initalization to
clutter_stage_osx_realize. Also showing the stage causes drawing
function but other part of the system(in particular conformance tests)
don't expect it and aren't ready at this moment.
Mention the XFixes extension for compositors using input regions to let
events "pass through" the stage.

When we disable the event retrieval, we now just disable the X11 event
source, not the event selection. We need to make that clear to
applications, especially compositors, which might expect complete
control over the selection.
Currently, we select input events and GLX events conditionally,
depending on whether the user has disabled event retrieval.
We should, instead, unconditionally select input events even with event
retrieval disabled because we need to guarantee that the Clutter
internal state is maintained when calling clutter_x11_handle_event()
without requiring applications or embedding toolkits to select events
themselves. If we did that, we'd have to document the events to be
selected, and also update applications and embedding toolkits each time
we added a new mask, or a new class of events - something that's clearly
not possible.
See:
http://bugzilla.clutter-project.org/show_bug.cgi?id=998
for the rationale of why we did conditional selection. It is now clear
that a compositor should clear out the input region, since it cannot
assume a perfectly clean slate coming from us.
See:
http://bugzilla.clutter-project.org/show_bug.cgi?id=2228
for an example of things that break if we do conditional event
selection on GLX events. In that specific case, the X11 server ≤ 1.8
always pushed GLX events on the queue, even without selecting them; this
has been fixed in the X11 server ≥ 1.9, which means that applications
like Mutter or toolkit integration libraries like Clutter-GTK would stop
working on recent Intel drivers providing the GLX_INTEL_swap_event
extension.
This change has been tested with Mutter and Clutter-GTK.
