Added Test program for 3D: 3DStudio. Allows testing of almost every 3D command interactively on a PSP to compare with the results on Jpcsp.
r1234
Improved TFUNC video command (e.g. DECAL mode). Tested on PSP. Allow partial matrix loading (view, model, texture, projection): start index is given at start command. Both fixes should improve a few 3D games.
