Great stuff - I have pushed your patch, and also my patches to default
to Lanczos filter.  Can you please add an example of "before" and
"after" where the advantages of the Lanzcos filter are nicely visible to
the Release Notes (http://wiki.documentfoundation.org/ReleaseNotes/3.6)?

Adding the QA list to the CC: - thanks to Tomaz, we have changed the
default of the image resize operations to a new scaling operation.
Please be careful about bugs that involve scaling of images, quality of
eg. PDF output, or speed of such operations.

Tomaz - what interests you next? :-)  You've already outlined some ideas
regarding the filters, correct?

Thank you a lot,
Kendy
