First attempt at a triangle plotter

Two EXE's - one shows my plotter (gTriangleFill), the other plots triangles using PLOT 85. Currently mine's about 50% faster than PLOT 85 for non-clipped triangles, and only ~5%/average faster for clipped. The GDI's plotter (the Windows graphics function which BB4W relies on) is not slow; I expected my routine to be at least twice as fast. Overall (especially for clipped triangles), the underlying GDI routines are probably faster.

David.
