This adds support for compressed textures to the r100->r500 CS
checker, it lets me run openarena and the demos in mesa fine,
If someone can check the size calcs for DXT1/35 the w//h changes
that would be nice.

The calculations are wrong.
E.g. for image 16 x 16, format is DXT3 (block size = 16 bytes, block width =
4, block height = 4) the size is 256. Yours code would calculate it as 16 *
(16 / 4) = 64.
The proper way to calculate it is
unsigned wblocks = (width + blockWidth - 1) / blockWidth;

Thanks to Maciej Cencora for initial comments.
Changes since v1:
fix calculations with Maciej formulas
