that wouldn't be bilinear anymore i guess. sure, gaussian or lanczos
could be implemented, but for a fast start bilinear or perhaps bicubic
should be sufficient. doing it in hsl colorspace should prevent artifacts,
and the whole thing will be pretty small and easy to code.

no idea what the hell happened last time :/
