Fixed buggy clipping when using projective transforms in GL 2 engine.

The gl_Position x, y, and z coordinates are always divided by the
homogenuous w coordinate to yield the final coordinates. Since we want
the depth to be constant for the whole item we need to premultiply it by
the w-coordinate. We can do this in the main() function in the vertex
programs since all the vertex programs use the depth uniform, thus
simplifying the programs a bit.
