Texel Locations changed also
Calculate 2x2 Texel locations to average
T00 = texel at (u0,v0) = texel at (u-0.5, v-0.5)
= (20.71H, 17.FC8H) = (32,23) (truncate)
T01 = texel at (u0,v1) = texel at (32, 24)
T10 = texel at (u1,v0) = texel at (33, 23)
T11 = texel at (u1,v1) = texel at (33, 24)
(1-0.441)(1-0.986)T00 + 0.441(1-0.986) T10 + (1-0.441)(0.986) T01 + 0.441(0.986)T11
