Subject [Bug 121233] Lanczos3 resampling for Bitmaps

--- Comment #9 from Tomaž Vajngerl <quikee@gmail.com> ---
I think SCALE_SUPER from Symphony should be default and used for bitmaps on the
GUI as it is as fast as SCALE_INTERPOLATE when scaling ratio is > 0.5, but much
better quality for scaling ratio < 0.5. 

Lanczos should be used when quality of scaling is more important than speed -
which means at (PDF) export or where the bitmap is persistently scaled. Others
resamplers like bicubic are better in some cases but should not be used unless
the (advanced) user explicitly chooses it. Currently there is no place where
this can be used.

The biggest problem for the users is that the quality of scaling is not good at
PDF export - this is where Lanczos should be used ASAP.

Re, Tomaž
