annotate include/begin_code.h @ 3541:0c429a5fda8a
Added an automated test for rectangle routines, currently only testing line clipping.
Use the Cohen-Sutherland algorithm for line clipping which uses integer math and preserves ordering of clipped points.
Removed getopt() support in testsdl.c, replaced with simple argv scanning.
