e319fc217b Hold the maximum X and Y coordinate in variables instead of calculating them 
when needed. The variables make signed compares in the line clipper easier.

5304a8149e Changes to the TGI driver API: 
* Removed CIRCLE
  * Aspect ratio is a new header variable
  * Removed the reserved bytes - it's easier to bump the API version
  * Clipping is done completely in the wrapper

f24adadb9c Added a first version of a Cohen Sutherland line clipper. This version 
basically works, but has rounding problems and an intermediate result overflow
in the multiplication, which causes for larger lines.
