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.

dd625fca71 When going from 344(3/4) pixels to 4555, the alpha channel only has a zero appended to it. Hence we must clear that bit for each pixel that was transparent during decoding. 2013-09-10 13:22:53 -04:00

91c79cd717 Fix Bilinear upscale
There were a couple of fixes.

1. Add another set of pixels to an image that represent the fractional bits that get populated as a result of doing a bilerp.
2. Do not consider individual axes when doing the bilerp. Instead, assign a weight to each of the different texels that we will use for the bilerp. Then, combine them and save the fractional bits.
