Is there a way to blit from the screen? I tried screen_blit, and it =
returns a black rectangle, and I tried blit and that returns a mixed up =
image...not even like how it should look. Help please!

There is not a foolproof way to read from the screen. Get_pixel might work,
but the *_blit routines are not made to read directly from the screen. The
reason this is because the screen memory might be banked (SVGA modes) or
planar (modeX) which means I would have to write a new routine for reading
from the screen for each type of display memory organization. Modes that
are Linear should have no problems reading from the screen.
