Implement a basic separable bilinear filter to rescale the quantizer offsets. Structure inspired by swscale, but floating-point instead of fixed-point. Not as optimized as it could be, but it's quite fast already. Example compression penalties on a 720p video game recording: First pass with 720p and second as 480p: ~-1.5% (vs. same res) First pass with 480p and second as 720p: ~-3% (vs. same res)
