James Park fede4fb784 libobs: Improve low-resolution bilinear sampling 
The issue with the current bilinear_lowres_scale effect is that it
samples adjacent texels, disregarding the texel-to-pixel ratio. If the
ratio is large, this can lead to aliasing. This change provides a fair
set of texture samples across the entire pixel.

The 8-sample pattern used here comes from Direct3D.
