Hardware-accelerated ALPHATEMPLATE blits

Post by chris »

Pretty self explanatory, but please can some form of hardware accelerated ALPHATEMPLATE blits be added to graphics.library.
They are needed for blitting anti-alised glyphs produced by diskfont.library/BulletAPI, and using BltBitMapTags is massively slower than the same blit for a non-alpha template.

Replying to myself, but... it looks like COMPFLAG_Color1Modulate might help with this if the ALPHATEMPLATE is passed as COMPTAG_SrcAlpha. However the source bitmap (which is then surely irrelevant?) would still need to be specified, and presumably the right size.
