Most people new to graphics programming use the first option - they update
the whole screen every frame. The problem is that this is unacceptably
slow for most people. Calling update() takes 35 milliseconds on my
machine, which doesn't sound like much, until you realize that 1000 / 35 =

28 frames per second maximum. And that's with no game logic, no blits, no
input, no AI, nothing. I'm just sitting there updating the screen, and 28
fps is my maximum framerate. Ugh.

- think of a smooth-scrolling engine like an overhead real-time strategy
game or a side-scroller. So what do you do in this case? Well, the short
answer is - don't write this kind of game in pygame. The long answer is to
scroll in steps of several pixels at a time; don't try to make scrolling
perfectly smooth
