I don't appreciate the differences between interpolation and sampling,
and I'm certain my (end)users wouldn't.
Whatever Cairo eventually offers, I will likely just wrap+expose with
abstract FAST/GOOD/BEST options (At least, until a knowledgeable user
needs more specific control, if ever ...)

PS: My more interesting downscaling concern/goal would be about
downscaling *huge* source images to a reasonable (ie on-screen) size,
but that's probably a whole different discussion ...
