This adds three new texture backends. - CoglTexture2D: This is a trimmed down version of CoglTexture2DSliced which only supports a single texture and only works with the GL_TEXTURE_2D target. The code is a lot simpler so it has a less overheads than dealing with slices. Cogl will use this wherever possible. - CoglSubTexture: This is used to get a CoglHandle to represent a subregion of another texture. The texture can be used as if it was a standalone texture but it does not need to copy the resources. - CoglAtlasTexture: This collects RGB and RGBA textures into a single GL texture with the aim of reducing texture state changes and increasing batching. The backend will try to manage the atlas and may move the textures around to close gaps in the texture. By default all textures will be placed in the atlas. |

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.
