Detailed Description

Collects all graphic operations and updates the screen on destruction When porting ASC from DOS to SDL, the problem arose that under DOS all graphic operations directly modified the graphics memory and were directly visible without any overhead.

Using SDL, the operations operated on a buffer that had to be copied to display memory in a seperate operation, which was costly. Updating the screen after every basic graphic operation was too expensive, so I wrote this class that suspended all updates until it was destructed.
