notes:

Your code color a pixel whose center is not
inside the polygon at the end of the scan 
line.

You want to sample color and depth at the
CENTER of a pixel.  Thus, if the starting
value of x is not at the center of a pixel
you need to calculate an offset to adjust
where you sample color and h.

You do not compute intersections correctly.

There are visible cracks between polygons 
when rendering certain shapes.

In otehr words, your problem set has some 
serious problems.
