Support new type of Studio texture projection

[LasseD]

Studio has released a new way of projecting textures. It appears that PE_TEX_INFO is used for the mapping data. The usage of parameters has to be reverse engineered.

The new type of Studio data looks like this:

0 PE_TEX_PATH 0 0
0 PE_TEX_INFO 0.0000 0.5417 -0.9150 1.6100 0.0000 0.0000 0.0000 0.0000 0.6708 0.0000 0.2200 0.0000 -20.0000 26.0000 20.0000 -22.0000

rather than what was previously expected:

0 PE_TEX_INFO
