Fill the z buffer. The face buffer is not operated on!

This is one of the z buffer fill functions called in zbufclip() and zbufwireclip().

Parameters:
v1[4 floats, world coordinates] first vertex
v2[4 floats, world coordinates] second vertex
v3[4 floats, world coordinates] third vertex

Fill the z buffer, but invert z order, and add the face index to the corresponing face buffer.

This is one of the z buffer fill functions called in zbufclip() and zbufwireclip().

Parameters:
v1[4 floats, world coordinates] first vertex
v2[4 floats, world coordinates] second vertex
v3[4 floats, world coordinates] third vertex
