When running in a purely swrast environment (such as with
LIBGL_ALWAYS_SOFTWARE), the extension is not exposed by mesa,
but wayland is still possible with wl_shm.

Seeing 'fail' in the test reports and the explanation that it means
"Test failed, but it was an expected failure" somewhat gives the
impression that these failures are ok. Actually these failures represent
known bugs/issues that we haven't yet fixed but we don't want them to
result in 'make check' ailing. To try and better reflect the severity of
these issues we now report them as 'FIXME'.

It was an oversight when making the CoglAtlasTexture api public that we
continued to use the COGL_TEXTURE_INTERNAL_DEFINE macro. This updates
the code to now use COGL_TEXTURE_DEFINE which means the
cogl_is_atlas_texture() function will now be exported in the public api.

The solution files which are updated due to the split of Cogl-Path need
to be pushed as well, which were forgotten. Sorry about this, and fix
.def file generation on Cogl with SDL on Visual Studio 2010 builds.
The recommended usage model for rendering pipelines with minor changes
is to make a copy of a base pipeline just before rendering and then
modify that. The new pipeline can then be used as the base pipeline
for the next paint. Currently this has a known problem when modifying
uniform values in that Cogl won't prune the redundant ancestry and
instead it will end up with an ever-growing chain of pipelines. This
is particularly bad for something like CoglGST where it could also end
up leaking textures for the video frames if the pipelines are used to
render video.
The patch adds a test case for that situation so that we won't forget
about the problem. The test is maked as a known failure. Additionally
the patch adds a similar test for setting the blend constant to
constrast the test with some state that does work correctly.

For some reason the unit test symbols end up in the read-only data
section when building on windows rather than the initialised data
section so they have a different letter in the list generated by nm.
They also begin with an underscore because windows likes to add
underscores to symbols for some reason. This patch changes the regular
expressions in the code to generate the wrapper list so that it
accepts either way.

The unit tests were failing to build with mingw32 because the
libtest-fixtures was being included both by libcogl and the
test-conformance and test-unit executables. That meant that the
symbols were defined twice and it wouldn't link.
The rule which depends on test-unit being built needs to be called
test-unit.exe on Windows so this patch fixes it to use the $(EXEEXT)
variable to get the right name.

This reverts the change in semantics for cogl_texture_new_with_size so
that it goes back to allocating textures synchronously and returning
NULL if there was a failure to allocate. Only the new/2.0 texture apis
will have the lazy allocation behaviour so we avoid breaking existing
code. This also fixes a potential crasher by removing a code path
that was passing NULL to cogl_texture_allocate() that would have caused
and abort if there were an error.

This adds a centralized autotools Makefile to be used in the completion
of the project files for Cogl-Path for now, which can be used also in
Cogl, Cogl-Pango and possibly Cogl-Gst so that we could have less clutter
in the autotools files.
This patch set will also allow the Cogl-Path project files to be filled in
during 'make dist' and make them distributed during a tarball release.

This adds a modification to the test-point-sprite test which uses a
shader snippet which directly references cogl_point_coord instead of
relying on cogl_pipeline_set_layer_point_sprite_coords_enabled to
replace the texture coordinates with the point coords.

This adds a #define for gl_PointCoord to all shaders so that it can be
accessed with a name in the Cogl namespace.

Previously we would only add the #version pragma to shaders when
point sprite texture coordinates are enabled for a layer so that we
can access the gl_PointCoord builtin. However I don't think there's
any good reason not to just always request GLSL version 1.2 if it's
available. That way applications can always use gl_PointCoord without
having to enable point sprite texture coordinates.
This adds a glsl_version_to_use member to CoglContext which is used to
generate the #version pragma as part of the shader boilerplate. On
desktop GL this is set to 120 if version 1.2 is available, otherwise
it is left at 110. On GLES it is always left as 100.

The documentation for the builtin varyings for the texture coordinates
was wrongly claiming that the varyings are stored in an array. This
was changed in e55b64a9cdc9 so that each layer gets its own
independent varying.
The documentation was also referring to texture units instead of layer
numbers. The texture units are no longer publicly exposed in the
shaders and instead everything should in theory be expressed in terms
of layer numbers.
