The nifty part is I don't think we need any additional storage. :) Something
like

R300_EASY_TX_FORMAT(ZERO, ZERO, ZERO, ONE, X8)

should do the trick I think.

Use PICT_FORMAT_A() instead of PIXMAN_FORMAT_A() (see
/usr/include/xorg/picture.h). If you don't mind, I can push the patch with
those two changes.
