clarify that it only changes the subset of tests, not the actual versions
of the tests run.

Add test for Chromium crash when a GPU buffer is deleted

When preserveDrawingBuffer is true and WebGL context leaves a vertex
attribute array != 0 enabled while deleting the buffer attached to that,
Chromium's (at least up to version 33) GPU process will crash when
copying the WebGL drawing buffer. Reproduces at least on NVIDIA OpenGL
drivers.
