BltMask:
by me: optimize by replacing the maskbit table with a byte containing the maskbit and rotating using _rotr8. Also move the comparison out of the loop, making 2 loops, one with pattern, one without. By Evgeniy Boltik: Optimize by using function pointers. Fix calculation of brush position. By me again: optimize the fix by moving the calculation out of the outer loop. svn path=/trunk/; revision=40277
