Hash :966c940b Message :Fix validation for compressed texture functions.
* No validation that the format matched the texture level's format for
SubImage calls.
* WebGL does not allow the base level to be smaller than the block size.
* ANGLE used to allow mips of size 3 when this is disallowed.
* Don't early-exit validation when dimensions are 0, imageSize validation
happens later.
