1776ac8ed5 Remove internal usage of ClutterGeometry in StageWindow
The ClutterGeometry type is a poor substitute of cairo_rectangle_int_t,
with unsigned integers for width and height to complicate matters.

Let's remove the internal usage of ClutterGeometry and switch to the
rectangle type from Cairo.

e381a159a7 Remove unused _cogl_swap_buffers_notify
Recently _cogl_swap_buffers_notify was added (in 142b229c5c) so that
Cogl would be notified when Clutter performs a swap buffers request for
a given onscreen framebuffer. It was expected this would be required for
the recent cogl_read_pixel optimization that was implemented (ref
1bdb0e6e98) but in the end it wasn't used.

Since it wasn't used in the end this patch removes the API.

734a236a97 wayland: fix shm buffers
We need to *write* to the shared memory, not read from it.
cogl_texture_from_data() is read-only, it doesn't keep
the data in sync with the texture.

Instead, we have to call cogl_texture_get_data() ourselves
to sync manually.

d4ccef786b wayland: make buffer handling generic
Separate the code specific to DRM buffers into
its own functions/subclass to prepare for adding SHM buffers.

15cd4705db wayland: really fix buffer format selection
Wayland visuals refer to a pixel's bytes in order from
most significant to least significant, while the
one-byte-per-component Cogl formats refer to the order
of increasing memory addresses, so converting between
the two depends on the system's endianness.

2ff5cf5aa0 wayland: fix pixel format
This matches to the Wayland premultiplied_argb_visual
the rest of the code is using.

The format needs to differ based on endianness, though...

f6a6a44fe7 wayland: clean up buffer creation code
The height was being set from the ClutterGeometry in some parts
and from the stage in others. And since both callers of this
function pass &stage_wayland->allocation as the geometry anyway,
the stage argument isn't really even needed.

142b229c5c cogl: Adds _cogl_swap_buffers_notify for clutter backends
This adds a stop-gap mechanism for Cogl to know when the window system
is requested to present the current backbuffer to the frontbuffer by
adding a _cogl_swap_buffers_notify function that backends are now
expected to call right after issuing the equivalent request to OpenGL
vie the platforms OpenGL binding layer. This (blindly) updates all the
backends to call this new function.

For now Cogl doesn't do anything with the notification but the intention
is to use it as part of a planned read-pixel optimization which will
need to reset some state at the start of each new frame.

134ce072e7 The amazing lazy-copy-back-repaint-page-flip
Always use pageflipping, but avoid full repaint by copying back dirty
regions from front to back.  Additionally, we dealy copying back until
we're ready to paint the new frame, so we can avoid copying areas that
will be repainted anyway.

This is the least amount of copying per frame we can get away with at all
and at the same time we don't have to worry about stalling the GPU on
synchronized blits since we always pageflip.
