Robert Bragg 8a5aed36fe pixel-array: Only allow allocation of arrays with a 2D size
This removes cogl_pixel_array_new which just took a size in bytes.

Without the image size and pixel format then the driver often doesn't
have enough information to allocate optimal GPU memory that can be
textured from directly. This is because GPUs often have ways to
spatially alter the layout of a texture to improve cache access patterns
which may require special alignment and padding dependant in the images
width, height and bpp.

Although currently we are limited by OpenGL because it doesn't let us
pass on the width and height when allocating a PBO, the hope is that we
can define a better extension at some point.

Outline of test categories:

The conform/ tests should be non-interactive unit-tests that verify a single
feature is behaving as documented. See conform/ADDING_NEW_TESTS for more
details.

The micro-bench/ tests should be focused perfomance test, ideally testing a
single metric. Please never forget that these tests are synthetec and if you
are using them then you understand what metric is being tested. They probably
don't reflect any real world application loads and the intention is that you
use these tests once you have already determined the crux of your problem and
need focused feedback that your changes are indeed improving matters. There is
no exit status requirements for these tests, but they should give clear
feedback as to their performance. If the framerate is the feedback metric, then
the test should forcibly enable FPS debugging.

The interactive/ tests are any tests whose status can not be determined without
a user looking at some visual output, or providing some manual input etc. This
covers most of the original Clutter tests. Ideally some of these tests will be
migrated into the conformance/ directory so they can be used in automated
nightly tests.

The data/ directory contains optional data (like images and ClutterScript
definitions) that can be referenced by a test.

Other notes:

• All tests should ideally include a detailed description in the source
explaining exactly what the test is for, how the test was designed to work,
and possibly a rationale for the approach taken for testing.

• When running tests under Valgrind, you should follow the instructions
available here:

        http://live.gnome.org/Valgrind

and also use the suppression file available inside the data/ directory.
