This series implements lanczos interpolation filter.
Andy, I have made some changes to the code. Can you test the
patches. I hope the artifacts are reduced this time.
The artifacts are still there.
:(
The higher levels involve a hell lot of calucations per pixel so the
decreased fps is expected. I was thinking of having only 2 levels for
lanczos filter ie. 2 and 4.
Christian, will it be fine if we only have 2 levels (with kernel size
2 and 4) of lanczos filter corresponding to HIGH_QUALITY_SCALING_L2
and L3?
2 and 4 still have the offset issue, which does sometimes cause the
white line.
I've found another issue with 2 and 4 = unscaled with a raster locked
res test the 1 pix detail will be lost. The detail does re-appear if you
scale up.
