I've reached a point in game development were I need the ability to scroll
the screen. Now normally I would simply redraw a different part of a bitmap
if the picture on the screen had to change. I have a problem in the sense
that I have to redraw a large number of bitmaps, which flickers and slows
down the game. 
What I would like ultimatly is a way of blitting the screen including areas
not on the screen at that particular time into a large bitmap that I can
the manipulate. 
If anyone has a better (meaning easier and faster) way of scrolling I would
really appreciate it. Sample code would be especially nice.
