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.
