All Textures from Mysteries of the Sith, including Playermodel textures just because someone might find a use for them (And because they were the .GOO file along with the nomral textures).
I'm not sure, but I believe this mioght also contain all of the Textures from Dark Forces II as well, as I noticed a large number of them, and MotS does reuse a number of textures.
I'm not completely certain.
