ConfigureNotify is delivered on window movements too, but there is no
need to queue a relayout on these as the viewport hasn't changed size.
Check for the window actually changing size on ConfigureNotify before
queueing a relayout.
This fixes laggy window movement when moving a window in response to
Clutter mouse motion events.
The size and position of the window rectangle for clipping in
try_pushing_rect_as_window_rect is calculated by projecting the
rectangle coordinates. Due to rounding errors, this can end up with
slightly off numbers like 34.999999. These were then being cast
directly to an integer so it could end up off by one.
This uses a new macro called COGL_UTIL_NEARBYINT which is a
replacement for the C99 nearbyint function.
It was passing the number of vertices to
cogl_vertex_buffer_draw_elements but instead it should take the
maximum index which would be the number of vertices minus one. This
was causing errors to be reported with the checks filterset of Bugle.
If an actor is lying on the border of the Stage it might miss the LEAVE
event when the pointer of a device leaves the Stage window. Since the
backend is unsetting the Stage back pointer on the InputDevice we can
queue the emission of a LEAVE event on the pointer actor as well.

As well as manually setting the geometry size, we needed to queue a
relayout. This is what the ConfigureNotify handler would normally do,
but we don't get this event when using a foreign window (obviously).
This should fix resizing in things like gtk-clutter.
If we get into the resize function and it's a foreign window, set the
geometry size so that the allocate will set the backend size and call
glViewport.
Setting/unsetting fullscreen on a mapped or unmapped window now works
correctly.
If you unfullscreen a window that was initially full-screened, it will
unset the fullscreen hint and the WM will likely push the size down to
the largest valid size.
If the window was previously un-fullscreened, Clutter will restore the
previous size.
Fullscreening also now works if the WM switches the hint without the
application's knowledge (as happens when you resize a window to the size
of the screen, for example, with stock metacity).
Since all conformance tests share the same state we should not touch
stuff like the stage size; sharing is already fairly complex and adds a
lot of caveats on the implementation of a conformance test unit, and if
we make tests influence later ones then we might slip in bugs or false
negatives - thus defeating the whole point of a conformance test suite.
If FBOs aren't supported then it will end up very slow to reorganize
the atlas. Also currently the CoglTexture2D backend will refuse to
create any textures anyway so the full atlas texture won't be created.
cogl_texture_2d_new may fail in certain circumstances so
cogl_atlas_texture_reserve_space should detect this and also
fail. This will cause cogl_texture_new to fallback to a sliced
texture.
Thanks to Vladimir Ivakin for reporting this problem.
The g_assert_cmpint() macro prints out not just the assertion condition
but also the assertion contents; this is useful to catch wrong values
without incrementing the verbosity of the test itself.
When we resize, we relied on the stage's allocate to re-initialise the
GL viewport. Unfortunately, if we resized within Clutter, the new size
was cached before the window is actually resized, so glViewport wasn't
being called after resizing (some of the time, it's a race condition).
Change the way resizing works slightly so that we only resize when the
geometry size doesn't match our preferred size, and queue a relayout on
ConfigureNotify so the glViewport gets called.
Also change window creation slightly so that setting the size of a
window before it's realized works correctly.
Since the "internal" state is global, it will leak onto actors that you
didn't intend for it to, because it applies not just to the actors you
create, but also to any actors *they* create. Eg, if you have a dialog
box class, you might push/pop_internal around creating its buttons, so
that those buttons get marked as internal to the dialog box. But
ctx->internal_child will still be set during the *button*'s constructor
as well, and so, eg, the label and icon inside the button actor will
*also* be marked as internal children, even if that isn't what the
button class wanted.
The least intrusive change at this point is to make push_internal() and
pop_internal() two methods of the Actor class, and take a ClutterActor
pointer as the argument - thus moving the locality of the internal_child
counter to the Actor itself.

The master clock might have a Stage during its destruction phase,
without a StageWindow attached to it. If this happens and we try
to dereference the StageWindow to get its class and call a virtual
function we might experience some slight turbulence and... then...
explode.

The signal-swapped-after:: modifier for signal connection inside the
clutter_actor_animate* variadic arguments functions is not mentioned in
the documentation.
In the frenzy of the last 10mins before API freeze, I obviously forgot
to update the OpenGL path for _cogl_buffer_hints_to_gl_enum(). This
commit fixes this.
When the atlas is reorganised we could potentially be moving around
textures that are already referenced in the journal. We therefore need
to flush the journal otherwise they will be rendered with incorrect
texture coordinates. We also need to flush the journal even if we are
not reorganizing so that we can rely on the old texture contents
remaining in the atlas after migrating a texture out.
When creating a Cogl sub-texture, if the full texture is also a sub
texture it will now just offset the x and y and reference the full
texture instead. This avoids one level of indirection when rendering
the texture which reduces the chances of getting rounding errors in
the calculations.
Since get_paint_opacity() recurses through the hierarchy it might lead
to a lot of type checks while we walk the parent-child chain. We can
split the recursive function from the public entry point and perform the
type check just once.
• Remove unused variables.
• Do not pre-initialize ClutterActor's GType; pre-emptive optimizations
like these are more black magic than real optimization.
Remove an useless assignment. The n_expand_children is not used outside
the extra_space check, and if n_expand_children is 0 then the extra
space we allocate is 0.
