trans/movement alpha blending

The title pretty much sums it up. I'd like to do a static, per pixel, alpha blend.

Yeh, thats a good one! It always annoys me that I cant to alpha blending in movements, it would make so many things faster (unless the blending slowed things down that much)

If it was a static alpha map, then yes it would be faster than DM alpha, because that is interpolated before blended.
