fixed an off by one error I created in the texture copy function in bpstructs.cpp. SSBM no longer has black on ground. sorry about that ;p

noticed the real HW doesn't clip some things it should. modified the projection matrix to account for this.
changed normal loader to better handle 1 or 3 index NBT data which fixed an underrun.
added missing z component in biasing section of indirect texturing.
