gdk-pixbuf Lanczos scaling support



If I run out and write a patch to add support for the Lanczos scaling
algorithm to gdk-pixbuf, even though doing so would add another
scaling type, is there any chance that it would get added, or are the
scaling types, being part of the API, fixed in stone between major
releases?

Lanczos seems to be relatively slow, but produces top-notch results
for nearly all images -- the excellent freeware IrfanView for Windows
uses it for scaling, and ImageMagick uses it as the default scaling
algorithm.  Gqview, on the other hand, has only HYPER, as gdk-pixbuf
lacks support for Lanczos.
