3881fd3259 Adds cogl_framebuffer_draw_[*_]rectangle functions
This adds experimental 2.0 api replacements for the cogl_rectangle[_*]
functions that don't depend on having a current pipeline set on the
context via cogl_{set,push}_source() or having a current framebuffer set
on the context via cogl_push_framebuffer(). The aim for 2.0 is to switch
away from having a statefull context that affects drawing to having
framebuffer drawing apis that are explicitly passed a framebuffer and
pipeline.

To test this change several of the conformance tests were updated to use
this api instead of cogl_rectangle and
cogl_rectangle_with_texture_coords. Since it's quite laborious going
through all of the conformance tests the opportunity was taken to make
other clean ups in the conformance tests to replace other uses of
1.x api with experimental 2.0 api so long as that didn't affect what was
being tested.

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

785e6375eb Adds a context arg to cogl_pipeline_new()
As we move towards Cogl 2.0 we are aiming to remove the need for a
default global CoglContext and so everything should be explicitly
related to a context somehow. CoglPipelines are top level objects and
so this patch adds a context argument to cogl_pipeline_new().

e69e41b2c7 tests: Add a utility function for reading a pixel
Most of the conformance tests read a pixel value and assert that it
matches a known value. However they were all doing this with slightly
different methods. This adds a common test_utils_check_pixel function
which they now all use. The function takes an x and y coordinate and a
32-bit value representing the color. It is assumed that writing a
known color is most convenient as an 8 digit hex sequence which this
function allows. There is also a test_utils_check_pixel_rgb function
wrapper which takes the components as separate arguments. This is more
convenient when the expected color is also calculated by the test.

6c0dd4aab1 tests: avoid redundant setting of projection/modelview
This removes some redundant initializing of the modelview matrix since
we can assume the initial state is already the identity matrix. The
explicit initialization was only really necessary when running as a
clutter test because there the default matrix isn't the identity matrix.

Also some calls to cogl_orth to change the projection matrix have been
moved into the test entry point functions instead of calling this in the
paint function. Again the previous style probably came about because
with clutter we always had to re-assert the projection but now we are in
full control of the projection and can assume it doesn't need
re-asserting once set.

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.
