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.
