The plan is to remove the cogl-auto-texture apis since they hide a bit too much from developers but currently the conformance tests depend on these apis in numerous places. For the conformance tests it makes some sense to continue using high level texture apis similar to the auto-texture apis since we may want to make broad variations to how textures are allocated as part of the testing running if that might help exercise more code paths. This patch copies much of the auto-texture functionality into some slightly more special purpose utilities in test-utils.c/h. Minor changes include being constrained to the public Cogl api and they also don't let you catch CoglErrors and just assume they should abort on error.
