I'm affraid I don't follow. Do you mean to day that the current drawing mode 
 applies to sprites too? Does draw_sprite() suffice for drawing a sprite 
with this drawing mode? What abour compiled sprites, how does that work?

Creating a sub-bitmap involves at least one malloc(), which is pathetically 
slow on some systems. Setting a few numbers isn't, so 'dynamic' clipping 
will be a lot faster. There's also the issue of drawing a sprite partially 
off screen, which is better done with clipping then creating and destroying 
subbitmaps as needed.
IMHO :)
