-/* Switch from orthogonal to perspective view.

- * Tricky: we want to maintain all of the zooms, rotations and translations
- * that have been applied already.  They're in our internal screen space (that
- * is, 640x480 ortho).  We can't simply leave them where they are, since they'll
- * be applied before the perspective transform, which means they'll be in the
- * wrong coordinate space.
- *
- * Handle translations (the right column of the transform matrix) to the viewport.
- * Move rotations and scaling (0,0 through 1,1) to after the perspective transform.
- * Actually, those might be able to stay where they are, I'm not sure; it's translations
- * that are annoying.  So, XXX: see if rots and scales can be left on the modelview
- * matrix instead of messing with the projection matrix.
- *
- * When finished, the current position will be the "viewpoint" (at 0,0).  negative
- * Z goes into the screen, positive X and Y is right and down.
