The background vignette currently fits itself to the painted
texture, instead of the monitor. This causes some very
wrong looking drawing for backgrounds that don't fill the screen.
This commit reworks the vignette shader code to be clearer, more
correct, and parameterized so that it knows how to scale and
position the vignette.

The WALLPAPER style of background painting currently
draws starting in the upper left corner of each monitor.
This isn't really correct, it means the seam between
monitors doesn't match up and edges look unbalanced if
the tile isn't a multipe of monitor size.
Really, the tiles should be centered in the middle of
the screen. (Just like when tiling a bathroom floor,
tiles should start in the center of the room.)
This commit reworks the math to make that happen.

Commit 4f2bb583bf8c7f started to use a clutter_threads_add_repaint_func_full
callback instead of connecting to the stage's paint signal.
The callback has to return TRUE if it wants to be called again, so fix that
as we want to call it for every frame (otherwise apps supporting the WM SYNC
protocol will stop drawing).

Doing so causes useless full stage redraws and breaks culling
as clutter cannot know how the signal handler affects painting.
So use clutter_threads_add_repaint_func_full with the
CLUTTER_REPAINT_FLAGS_POST_PAINT flag instead.

gnome-shell shouldn't announce to the session manager it's
"ready" until it's fully initialized. It currently tells
the session manager it's ready as soon as it hits the main
loop. This causes nautilus in classic mode to start before
we have workspaces initialized.

During compositor grabs, all global keybindings that don't go
through mutter's keybinding system are blocked. To allow other
processes to make use of it, gnome-shell will expose a simple
grab API on DBus; for this, add API to grab key combos directly
instead of parsing accelerators stored in GSettings.

Some public headers were added, so these need to be "installed" as well.
Also clean up the preprocessor definitions as they were meant to be
in cogl/cogl-defines.h.
There is currently code to try to fill gradients in a
hardware native format, using #ifdefs. That optimization is
unimportant since gradients only use 2 byte buffers. It's
also incorrect because it's getting the channel order wrong
at buffer initialization time.
This commit drops the ifdefs for clarity and fixes the
channel order.

meta_screen_get_monitor_for_rect will return the monitor that
a given rect belongs in (choosing the "best" monitor based on
overlap, if there are overlapping monitors).
It doesn't work with 0x0 rects, though.
This commit fixes that.

Previously the sampler uniform declarations such as cogl_sampler0 were
generated by walking the list of layers in the shader state. This had
two problems. Firstly it would only generate the declarations for
layers that have been referenced. If a layer has a combine mode of
replace then the samplers from previous layers couldn't be used by
custom snippets. Secondly it meant that the samplers couldn't be
referenced by functions in the declarations sections because the
samplers are declared too late.
This patch fixes it to generate the layer declarations in the backend
start function using all of the layers on the pipeline instead. In
addition it adds the sampler declarations to the vertex shader as they
were previously missing.

This adds hook points to add global function and variable declarations
to either the fragment or vertex shader. The declarations can then be
used by subsequent snippets. Only the ‘declarations’ string of the
snippet is used and the code is directly put in the global scope near
the top of the shader.
The reason this is necessary rather than just adding a normal snippet
with the declarations is that for the other hooks Cogl assumes that
the snippets are independent of each other. That means if a snippet
has a replace string then it will assume that it doesn't even need to
generate the code for earlier hooks which means the global
declarations would be lost.

This fixes some minor errors and warnings that were preventing Cogl
building with mingw32:
• cogl-framebuffer-gl.c was not including cogl-texture-private.h.
Presumably something else ends up including that when building for
GLX.
• The WGL winsys was not including cogl-error-private.h
• A call to strsplit in the WGL winsys was wrong.
• For some reason the test-wrap-rectangle-textures test was trying to
include the GDKPixbuf header.

The version of Pango that the script downloads is using G_CONST_RETURN
in the public headers. This won't build if G_DISABLE_DEPRECATED is
enabled so instead the build script now just recommends to pass
--enable-deprecated to cogl's configure script.

Cogl now requires at least version 2.32.0 of GLib. There are no
pre-built binaries for this from tml so we have to build glib from
source. This also requires libffi. The binary packages for libffi and
zlib don't install a pc file so the script just manually generates a
fake one.

Instead of directly accessing the instance fields. This removes a
compiler warning after the constification of g_get_prgname(), and it
seems to me to be generally more correct.
Instead of using a custom apply_transform(), paint(), and pick()
implementations, we can simply apply a transformation to the children of
a ScrollActor.
