-NOTES
-Special versions: fast Y 1:1 scaling (no interpolation in y direction)
-
-TODO
-more intelligent misalignment avoidance for the horizontal scaler
-write special vertical cubic upscale version
-optimize C code (YV12 / minmax)
-add support for packed pixel YUV input & output
-add support for Y8 output
-optimize BGR24 & BGR32
-add BGR4 output support
-write special BGR->BGR scaler
