Instead of returning a sub-pixel height round up the preferred height to
the nearest integral value that is not less than the size reported by
Pango, once converted in pixels.
(This is inspired by Metacity commit 45cbaa2 by Thomas Thurman, but
much simpler - the use of g_date_strftime("%Y") ended up being just
%d for all 90+ current translations)
This fixes some backwards logic for asserting that we have a GLX major
version == 1 and a minor version >= 2. (NB: Although we technically
depend on GLX 1.3 features, we still have to support drivers that report
GLX 1.2 because there are a lot of mesa drivers out there incorrectly
report GLX 1.2 even though they export extensions that depend on GLX
1.3)
meta_workspace_set_builtin_struts() is slightly expensive; it involves
discarding all our cached computed information about the layout of the
workspace. So catch calls to set_builtin_struts() that don't change
anything.

A material layer can not be considered equal if it is using different
texture filtering modes. This was causing problems where rectangles
with different filters would end up batched together and then rendered
with the wrong filter mode.

If your OpenGL driver supports GLX_INTEL_swap_event that means when
glXSwapBuffers is called it returns immediatly and an XEvent is sent when
the actual swap has finished.
Clutter can use the events that notify swap completion as a means to
throttle rendering in the master clock without blocking the CPU and so it
should help improve the performance of CPU bound applications.
Some extensions only support GLX versions > 1.3 and may not support
old style X Windows as GLXDrawables, so we now create GLXWindows for
stages when possible.
Since meta_workspace_invalidate_work_area() frees the edges
workspace->screen_edges and workspace->monitor_edges, we must clean up
our cached edge resistance data when the invalidate_work_area() is
called on the active workspace, or when the workspace changes.
Make the computation of the edge resistance data lazy so that it
will be recomputed the next time we try to access it.
meta_display_compute_resistance_and_snapping_edges() is made
private to edge-resistance.c
Invaliding the data when active workspace changes also will improve
correctness for edge resistance when the current workspace changes
during a grab operation. (Even with this fix we still don't try to
handle window positions changing during a grab operation; that can't
cause a crash since, unlike screen and monitor edges, the window edges
are freshly allocated, it will just cause slight oddness in that
corner case.)
Root cause tracked down due to much effort by Jon Nettleton.

Commit d2bdd3cb62 fixed some compiler warnings but also broke the
ability to create a stage. Although not having warnings from the
compiler is nice, it is also nice to be able to create a stage so lets
not invert the meaning of the error check.
The function modifies the pixels pointed by p in-place so the pointer
can not be constant. The compiler was accepting this because the
modification is done from inline assembler.

Gtk-doc is reporting a lot of false positives in the unused text file,
mostly because of new private files that have been added to Cogl but not
to the gtk-doc ignore list for the Cogl API reference.
Once the false positives have been removed we have a couple of really
missing symbols that should be added to the cogl-sections.txt file.

The PixelFormat bit and mask #defines should not be used and are there
mostly for convenience, so we can push them to the "private" sub-section
of the API reference.
This pushed Cogl's API reference coverage to 100%.

The test was calling g_object_get to fetch the "opacity-start" property
(unsigned int) into a guint8 local variable. It's a bit of a mean trap
given that the getter function returns guint8 values so this also adds a
comment explaining what's going on.
_cogl_texture_driver_gen is needed to set the texture minification
mode to Cogl's default of GL_LINEAR. There was also a line to set this
in _cogl_texture_2d_new_with_size but it wasn't working because it was
called *before* the texture was bound. If the texture was later
rendered with the default material it then it would end up with GL's
default mipmap filtering mode but without mipmaps so it would render
white squares instead.

This adds a fast path for premultiplying an RGBA image using SSE2
instructions. SSE registers are 128-bit and we need at least 16-bits
per component for the intermediate result of the multiplication so we
can do two pixels in parallel with one register. The function
interleaves 2 SSE registers to multiply 4 pixels in one function call
with the hope that this will pipeline better.

• Add the function name in the warning, since the text is the same in
both clutter_actor_raise() and clutter_actor_lower().
• If an actor has a name then prefer it to the type name.
