b85f2e907a tests: Add a test which writes all pixel formats
This adds a test similar to the test-read-texture-formats test but
that updates data on a 1x1 pixel RGBA texture instead. On GLES2 this
should end up testing all of the convesion code because in that case
GL only supports reading back RGBA data.

70dfbdd5e3 tests: Test reading all pixel formats
The test-read-alpha-texture test has been replaced with a test that
tries reading an RGBA texture in all current pixel formats. On GLES2
this should end up testing all of the convesion code because in that
case GL only supports reading back RGBA data. The test now works on
GLES2 since the conversion code for all of the formats has been added
so this also removes the GL requirement.

b6dc23370d Add a conformance test for reading back an RGBA texture as alpha-only
This just creates a 1x1 RGBA texture and then reads it back in
COGL_PIXEL_FORMAT_A_8 format. Gnome Shell is doing this to create a
shadow and I accidentally broke it so this should hopefully stop that
happening again.

bbcbece6c9 tests: Improve thoroughness and reporting of make test
This patch reworks our conformance testing framework because it seems
that glib's gtesting framework isn't really well suited to our use case.
For example we weren't able to test windows builds given the way we
were using it and also for each test we'd like to repeat the test
with several different environments so we can test important driver and
feature combinations.

This patch instead switches away to a simplified but custom approach for
running our unit tests. We hope that having a more bespoke setup will
enable us to easily extend it to focus on the details important to us.

Notable changes with this new approach are:

We can now run 'make test' for our mingw windows builds.

We've got rid of all the test-*report* make rules and we're just left
with 'make test'

'make test' now runs each test several times with different driver and
feature combinations checking the result for each run. 'make test' will
then output a concise table of all of the results.

The combinations tested are:
- OpenGL Fixed Function
- OpenGL ARBfp
- OpenGL GLSL
- OpenGL No NPOT texture support
- OpenGLES 2.0
- OpenGLES 2.0 No NPOT texture support

47868e1f3e texture-3d: remove _EXP defines + CoglHandle and pass context
We are in the process of removing all _EXP suffix mangling for
experimental APIs (Ref: c6528c4b6c) and adding missing gtk-doc
comments so that we can instead rely on the "Stability: unstable"

This patch also replaces use of CoglHandle with a CoglTexture3D type

explicit CoglContext pointer but not a CoglTextureFlags argument,

bf7f1e358d Add a test for pipelines with sparse layer indices
There are currently quite a few places in Cogl where we muddle the
layer index and the texture unit number. The theory is that these two
numbers shouldn't be related and it should be possible to pick large
layer numbers with gaps.

This patch adds a test case to check that we can reference a large
layer number from a texture combine string by creating a pipeline with
only three layers but that have very large layer indices. This doesn't
currently work because Cogl interprets the numbers in the combine
strings to be the unit indices and not the layer indices. The
documentation however calls these numbers layer numbers so presumably
it is not meant to work that way.

There are probably many other bugs related to this that the test case
doesn't pick up so it would be good to add some more tests here, for
example to test that you can bind an attribute to the texture
coordinates for a large layer index.

92c3063014 framebuffer: Add cogl_framebuffer draw methods
This adds cogl_framebuffer_ apis for drawing attributes and primitives
that replace corresponding apis that depend on the default CoglContext.
This is part of the on going effort to adapt the Cogl api so it no
longer depends on a global context variable.

All the new drawing functions also take an explicit pipeline argument
since we are also aiming to avoid being a stateful api like Cairo and
OpenGL. Being stateless makes it easier for orthogonal components to
share access to the GPU. Being stateless should also minimize any
impedance miss-match for those wanting to build higher level stateless
apis on top of Cogl.

Note: none of the legacy, global state options such as
cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or
cogl_program_use() are supported by these new drawing apis and if set
will simply be silently ignored.

to skip over unset bits in single instruction. That way it will scale

ffsl is a non-standard function which glibc only provides by defining
GNUC_SOURCE. However if we are compiling with GCC we can avoid that
mess and just use the equivalent builtin. When not compiling for GCC
it will fall back to _cogl_util_ffs if the size of ints and longs are
the same (which is the case on i686). Otherwise it fallbacks to a slow
