The boilerplate for defining a GType for CoglFixed lived in
cogl-util.c but this didn't seem to make much sense seeing as nothing
in the cogl-util.h header file relates to CoglFixed and there is
already a separate C file for CoglFixed code. This also removes some
redundant header includes from cogl-util.c

This adds a test which tries manipulating some bits on a CoglBitmask
and verifies that it gets the expected result. This test is fairly
unusual in that it is directly testing some internal Cogl code that
isn't exposed through the public API. To make this work it directly
includes the source for CoglBitmask.
CoglBitmask does some somewhat dodgy things with converting longs to
pointers and back so it makes sense to have a test case to verify that
this is working on all platforms.

Instead of storing only 31 bits in the pointer for a CoglBitmask, it
now assumes it can store a whole unsigned long minus the one bit used
to mark whether it has been converted to a GArray or not. This works
on the assumption that we can cast an unsigned long to a pointer and
back without losing information which I think should be true for any
platforms that Cogl is interested in. This has the advantage that on
64-bit architectures we can store 63 bits before we have to resort to
using a GArray at no extra cost. The values in the GArray are now
stored as unsigned longs as well on the assumption that it is more
efficient to load and store data in chunks of longs rather than ints.

The coordinate transformation code is exercised throughout the
conformance and interactive tests, so there's no need to have a specific
interactive test that doesn't do anything more complicated than calling
clutter_actor_transform_stage_point().
We still ship clutter_get_show_fps() and clutter_get_debug_enabled() as
public entry points. Yet another case of missing API review prior to the
1.0 release, so really the bucket stops around my desk.
Let's deprecate these two useless functions, and reduce the API
footprint of Clutter.
This function should have never been made public in the first place; its
output depends on a configuration option of Clutter, and it's basically
useful only for internal debugging.
Make it consistent across the various build options (with or without
profiling enabled), and add a timestamp using the monotonic clock to
every debug message.
The clutter_get_timestamp() output depends on whether Clutter was
compiled with debugging support — it's meant to be used only by the
debugging notes, and it should not be used for anything else.
Instead of calling cogl_set_depth_test_enabled and
cogl_set_backface_culling_enabled ClutterDeformEffect now uses the
experimental CoglPipeline API. Those global state functions will soon
be deprecated in Cogl and they are implemented by flushing a temporary
override pipline which isn't ideal.
Using the new culling API we can also avoid having a separate buffer
of indices for the back of the texture by just changing the culling
mode to cull front baces instead of the back.

This changes ClutterDeformEffect to use a CoglAttributeBuffer with a
CoglPrimitive instead of the old CoglVertexBuffer. The old vertex
buffer code is now implemented in terms of the attribute buffer code
and it will eventually be deprecated. Using CoglPrimitives should be
slightly more efficient.
This also changes the struct we store the vertices to be
CoglVertexP3T2C4 instead of CoglTextureVertex. The latter is
technically not compatible with neither vertex buffers nor attribute
buffers because it contains a CoglColor and the internal members of
that are private so it is not valid to assume it contains 4 bytes and
use that as an attribute. Also it contains padding so it ends up
redundantly creating a larger buffer. CoglTextureVertex is in the
public API for the deform_vertex virtual so we still have to maintain
that. Instead of directly manipulating the array to upload, the
application is now passed a stack allocated temporary struct which
gets converted to a CoglVertexP3T2C4. This also means that we can map
the buffer as write only and still let the application read-write the
vertex.
The paint debug code to draw line strips for the deform mesh was
previously trying to set a red source material. However this wasn't
working because the material color was being overwritten by the color
attribute in the vertex buffer. This patch fixes that by creating a
seperate primitive for the lines and not adding the color
attribute. The lines code was also drawing both the front and back
indices. I don't think that entirely makes sense so I've just changed
it to draw only the front indices. Maybe painting both would make more
sense if backface culling was still enabled.

Update output DLL/LIB names to be consistent with the autotools output,
due to the newl-introduced multi-backend feature (only the Win32 backend
is supported here for now, GDK3 support will be added when it stabilizes)
The size of the framebuffer may not be the size of the framebuffer that we
requested - we should use the actual size of the framebuffer in the
calculations to position the crate in the center.

Cogl keeps a pointer to the last used onscreen framebuffer from the
context to implement the deprecated cogl_set_draw_buffer function
which can take COGL_WINDOW_BUFFER as the target to use the last
onscreen buffer. Previously this would also take a reference to that
pointer. However that was causing a circular reference between the
framebuffer and the context which makes it impossible to clean up
resources properly when onscreen buffers are used. This patch instead
changes it to just store the pointer and then clear the pointer during
_cogl_onscreen_free as a kind of cheap weak reference.

This tweaks the backface culling test to use the experimental pipeline
API as well as the legacy API. All of the primitives are now rendered
with all 16 combinations of front winding, cull face mode and legacy
state.
The test to 'draw a regular rectangle' has been removed. I think this
initially existed because their were different functions to draw a
rectangle with and without texturing. This is no longer the case so it
is no longer useful and it's awkward to implement because it need a
separate pipeline to disable the texturing.

When invalidating the deform effect, we are invalidating the vertices
shaping the deformation of an actor. Therefore, there is no need to
trigger a redraw of the associated actor, we can just repaint the
effect.
