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

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.

ec1c3406ad Add a conformance test for CoglBitmask
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.

b5a7657076 Starts porting Cogl conformance tests from Clutter
This makes a start on porting the Cogl conformance tests that currently
still live in the Clutter repository to be standalone Cogl tests that no
longer require a ClutterStage.

The main thing is that this commit brings in is the basic testing
infrastructure we need, so now we can port more and more tests
incrementally.

Since the test suite wants a way to synchronize X requests/replies and
we can't simply call XSynchronize in the test-utils code before we know
if we are really running on X this adds a check for an environment
variable named "COGL_X11_SYNC" in cogl-xlib-renderer.c and if it's set
it forces XSynchronize (dpy, TRUE) to be called.

By default the conformance tests are run off screen. This makes the
tests run much faster and they also don't interfere with other work you
may want to do by constantly stealing focus. CoglOnscreen framebuffers
obviously don't get tested this way so it's important that the tests
also get run on screen every once in a while, especially if changes are
being made to CoglFramebuffer related code.  On screen testing can be
enabled by setting COGL_TEST_ONSCREEN=1 in your environment.
