clutter_actor_allocate_preferred_size is supposed to use the fixed
position of an actor. Unfortunately, recent refactorings made it so
that it accidentally used the current allocation. As the current
allocation may be adjusted by the actor, or have been previously
allocated in a strange spot, it may have unintended side effects. Use
the fixed positioning of the actor instead.
This fixes weird issues with margins colliding with
ClutterFixedLayout, causing strange offsets on relayout.

The window positioning is delayed in idle_move_resize() in case the application
resizes/maximizes its window quickly after its creation. The delayed
positioning uses window->user_rect because of bug 426519 comment 3 (see
meta_window_move_resize_now()).
user_rect was not set in the initial positioning, causing the delayed
positioning unable to know which monitor we use for this window. As a
consequence, the window could jump spontaneously from one monitor to another.
With this patch, the window does not jump anymore.

The documentation said that you should return TRUE to mark
that the action was handled, but the code did the reverse.
Change the documentation to reflect what all the other gestures
do.

Otherwise, we'll have incorrect scrolling when we switch hardware
devices without switching virtual devices. For example, on a ThinkPad,
scroll using the touchpad, move the eraser mouse, and then scroll again:
the deltas will be wrong. This also matches what GTK+ does.

When trying to clamp to pixel a box that is exactly in between 2
pixels, the clutter_actor_box_clamp_to_pixel() function changes the
size of the box.
Here is an example :
ClutterActorBox box = { 10.5, 10, 20.5, 20};
g_message ("%fx%f -> %fx%f", box.x1, box.y1, box.x2, box.y2);
clutter_actor_box_clamp_to_pixel (&box);
g_message ("%fx%f -> %fx%f", box.x1, box.y1, box.x2, box.y2);
Here is what you get :
** Message: 10.500000x10.000000 -> 20.500000x20.000000
** Message: 10.000000x10.000000 -> 21.000000x20.000000
That is because of the properties of the ceilf and floorf function
used to do the clamping.
For example, ceil(0.5) is 1.0, and ceil(-0.5) is 0.0.
And, floor(0.5) is 0.0, and floor(-0.5) is -1.0.
To work around that problem this patch retains the distance between x
and y coordinates and apply that difference before calling ceilf() on
x2 and y2.

vtable
(Sorry, I had to re-apply Neil's patch as the original one somehow did
not apply)
The function prototypes for the GL functions in CoglContext have the
GLAPIENTRY attribute which on Windows makes them use the stdcall
calling convention. The function pointers exposed from cogl-gles2.h
don't have GLAPIENTRY so they end up having a different calling
convention on Windows. When Cogl is compiled there it ends up giving a
lot of warnings because it assigns a pointer to an incompatible
function type.
We probably don't want to make the functions exposed in cogl-gles2.h
use the stdcall calling convention because we control that API so
there is no need to introduce a second calling convention. The GLES2
context support currently isn't going to work on Windows anyway
because there is no EGL or GLES2 implementation.
Eventually if we make the Cogl GLES2 context virtualized on top of
Cogl then we will provide our own implementations of all these
functions so we can easily keep the C calling convention even on
Windows.
Until then to avoid the warnings on Windows we can just cast the
function pointers temporarily to (void*) when filling in the vtable.
This will also fix the build on Windows using Visual Studio, as it is
more picky on calling convention mismatches.

The ‘length’ for the swap chain is initially -1 which is supposed to
mean ‘no preference’. However, both of the SDL winsys's were
explicitly setting the SDL_GL_DOUBLEBUFFER attribute to zero in that
case which would try to disable double buffering.
On OS X, the equivalent to eglSwapBuffers (ie, [NSOpenGLContext
flushBuffer]) does nothing for a single buffer context. The
cogl-sdl-hello example does not specify the swap chain length so
presumably it would end up with a single buffer config. When
cogl_onscreen_swap_buffers is called it therefore does nothing and
nothing is painted.
I guess to make single-buffered contexts actually useful we should
expose some public equivalent to glFlush so that you can ensure the
rendering commands will actually hit the buffer. Alternatively we
could document that cogl_onscreen_swap_buffers performs this task on
single-buffered configs and then we could make the SDL winsys
explicitly call glFlush in that case.

As the overlay key works differently from normal keybindings, it
requires special treatment. However, by adding a rudimentary
MetaKeyBinding for it, we will be able to confine the special
handling to mutter and treat it like any other keybinding in
the shell.

Currently keybindings are blocked while the compositor holds a grab; if
we want a keybinding to be available anyway, we use captured ClutterEvents
to determine the KeyBindingAction the event would have triggered and
run our own handlers (ugh).
Instead, provide a hook to allow the compositor to filter out keybindings
before processing them normally, regardless of whether the compositor
holds a grab or not.

Since GTK+ commit b1ad5c8abc2c, GtkSetting's CSS provider uses a
priority of GTK_STYLE_PROVIDER_PRIORITY_SETTINGS, which means it
will overwrite the ones we create ourselves.
Bump the priority to fix dark window decorations.
