[Mesa-dev] [PATCH 1/2] r600g: texture offsets for non-TXF instructions

[Marek Olšák]

Not all tests have to be part of all.tests, like the
framebuffer_blit_scaled ones, because they are more strict than the
spec mandates.

However generally, all tests that it makes sense to test regularly
should be listed in all.tests. I only use quick.tests, which is the
only way I use piglit. I don't run tests manually unless I have to
based on a report from quick.tests.
