When blitting to a surface using the AlphaBltFast function, is it possible to have it replace the destination surface instead of "merging" the result of the blit between the source and alpha bitmap?
I currently fillrect the area where the blit will be placed on the destination surface, but it would be useful to have a flag or some other way to have AlphaBlt replace the background with the blit result.
