Glenn Maynard 056b85f83e The difference between the OpenGL ortho matrix we were constructing and ...

the OpenGL one is only that the Z value output was [0,1], instead of [-1,+1].
(I can't find D3D docs confirming that this is what D3D wants, but the math
lines up this way.)

Instead of setting up a different matrix from scratch, use OpenGL's well-
defined ranges, and then scale and shift the Z values to the range D3D wants.
