A bug in the triangle and line clipping code has been fixed. The bug caused the near clipping plane to be ignored. 

I also did some code cleanup and restructuring to reduce the overall code size of the software renderer. In the line and triangle clipping code now I don't use fixdiv any more. This is helpful for my plan to port this renderer to the 2nd CPU of the GP2X where the division functions are missing. There also were some other minor changes which were necessary to make everything compile without errors for the 940.
