Detailed Description

PVR vertex type: Textured sprite.

This vertex type is to be used with the sprite polygon header and the sprite related commands to draw textured sprites. Note that there is no fourth Z coordinate. I suppose it just gets interpolated?

The U/V coordinates in here are in the 16-bit per coordinate form. Also, like the fourth Z value, there is no fourth U or V, so it must get interpolated from the others.
