It looks like the intention was to duplicate an XVisualInfo in such a way
that the pointer could be returned and then later freed using XFree. But
Xalloc isn't an Xlib counterpart to XFree; Xlib doesn't provide a general
purpose malloc wrapper afik. By shuffling things about a bit, it was
possible to avoid the need for this hack.
By default, float * is considered as an out argument by gobject
introspection which is wrong for quite a few Cogl symbols. Start adding
annotations to fix that for the ones in the "Primitives" gtk-doc
section.

In the default implementation of container::destroy_child_meta Set child
meta qdata to NULL on the child and not the container, since the child
is the object that owns the data.
The lifetime of the journal VBO is entirely within the scope of the
cogl_journal_flush function so there is no need to store it globally
in the Cogl context. Instead, upload_vertices_to_vbo just returns the
new VBO. cogl_journal_flush stores this in a local variable and
destroys it before returning.
This also fixes an assertion when using the GLES backend which was
caused by nothing initialising the journal_vbo variable.

I just wasted a silly amount time trying to bisect an apparently broken
cogl-test-multitexture until I realized it was just silently failing to load
any textures.
If the system clock rolls back between two frames then we need
to account for the change, to avoid stopping the timeline.
The best option, since a roll back can be any arbitrary amount
of milliseconds, is to skip a frame.

The framebuffer_object spec isn't clear in defining whether attaching a
texture as a renderbuffer with mipmap filtering enabled while the mipmaps
have not been uploaded should result in an incomplete framebuffer object.
(different drivers make different decisions)
To avoid an error with drivers that do consider this a problem we explicitly
set non mipmapped filters before calling glCheckFramebufferStatusEXT. The
filters will later be reset when the texture is actually used for rendering
according to the filters set on the corresponding CoglMaterial.

This unit verifies that an Actor class will invoke the get_preferred_*
virtual functions unless the caching is in effect; it also verifies
that the cached values are correctly evicted.
The size requisition and allocation mechanisms should be thoroughly
tested to avoid unwanted regressions.
For starters, we can test the explicit size setting and the side
effects of calling clutter_actor_set_size().
Since an actor can only be parented to one container we don't need
the extra complications of maintaining a list of ChildMeta objects
attached to an actor in the default implementation of the Container
interface.
