Changed Bop_a8_set_alphapixel_Aop_argb() to be a fast path for real SRC_OVER DrawString() that uses DSBLIT_SRC_PREMULTIPLY and DSBLIT_BLEND_ALPHACHANNEL with SrcBlend = ONE and DstBlend = INVSRCALPHA. Other formats will follow.
Changed Bop_a8_set_alphapixel_Aop_argb() to be a fast path for real SRC_OVER
DrawString() that uses DSBLIT_SRC_PREMULTIPLY and DSBLIT_BLEND_ALPHACHANNEL
with SrcBlend = ONE and DstBlend = INVSRCALPHA. Other formats will follow.

Fixed DSDRAW_SRC_PREMULTIPLY if used used without blending.

Implemented DSBLIT_SRC_PREMULTCOLOR.

Added optimization for drawing blended with Src = ONE, Dst = ZERO.
