Does anyone have any information on the efficiency of the Blitter for line drawing? Specifically, I want to know if it checks for special case lines such as horizontal, vertical, and diagonal. The reason I would like to know is that I have a program where I can use a lot of conditionals and special case line drawing, or less conditionals and diagonal line drawing (although less diagonal lines than special case). I would like to know which would be faster. I suspect that the vertical line routines would be more efficient overall just because there would be far less to draw (about a third), and fewer conditionals . It will also produce more satisfactory results aesthetically.
