A direct access is a bit faster when you need to loop through the 
individual pixels (you can use _farnspeek/_farnspoke functions to speed 
up the farptr method, but it's still a bit slower than the direct 
access).  The nearptr direct access is more dangerous, because it 
effectively disables memory protection.

If you just move a buffer from or to the screen, use movedata() instead, 
which should be faster than both of the above methods.
