Pavel Krajcevski	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.	2013-09-06 01:58:53 -04:00
