Pavel Krajcevski	1115c2f9e4	Add 2BPP helper functions for our blocks. ... Namely, there are two things that we need to do: 1. Figure out the sub-mode based on the mode bit and the structure of the modulation data. The comments in Block.h describe how we do this. 2. For a given texel index, return 2BPP texel modulation bits.	2013-09-12 14:30:08 -04:00
