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.

Uninitialized textures could contain random bits. That makes the test
fail as glColorMask is used to let only one of the RGB pass through.

G_DISABLE_DEPRECATED is only intended for developers of Cogl and it
sometimes breaks the build for people just trying to build a
release. This patch adds an option to enable deprecated Glib
features. By default it is enabled for non-git versions of Cogl.
The patch is based on similar code in Clutter except it adds the flags
to COGL_EXTRA_CFLAGS instead of having a separate variable.

When testing with COGL_DEBUG=disable-npot-textures all of the tests
would fail because the testing infrastructure itself ends up creating
a sliced texture and then trying to use it as a render target. This
just modifies test-utils to use 512x512 for the size of the texture.

There is a currently a bug where pushing a buffer with a different
color mask will not cause the color mask to be flushed. This adds a
test to demonstrate that.

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.
