Patch with above described fixes
I'll attach a patch here that fixes 3 closely related issues with
acceleration of repeating sources/masks on the R300
- The code had an incorrect check for pitch (it was using a
value that already had been munged to register format)
- The code used only enabled the use of the TXPITCH register
for non-repeating sources but it works as well for repeating
in my testing. (This allows acceleration of width 1/2/4
repeating sources which are power-of-two but padded out.)
- In the rare case that a repeating source passed the
incorrect pitch check, the code didn't actually turn
repeat on in the accelerator.
I believe this fix is R300 specific and the R100/R200 code paths
are right.
