Keeps track of what is on top of under what.
A simple render class updating the erasearea information of all GUI
objects visible on screen. Handling screen updates on erase and
draw.
This should give you GUI objects you can freely move around under
or over other objects on screen. We probably won't use very
complicated screens so often, but this should handle it.
Notes: I'd really like thoughts on this. I'm thinking about
inheriting a render class from pygame.sprite, but I can't
find a real good use for it yet.
Todo: Need to optimize the update functions. Only update rectangles
which have coordinates inside the changing rectangle, only save
the needed part of the the background.
Implement 'raise' and 'lower' when I need them.
