Title: allow non power of two tiles, and correct code for all filters

Could we backport this to the 0.10.x line? Fixes ticket #2853 in the Arnold trac.

This is part of commit a35fdcda2de "TextureSystem: allow subimages specified by name, and alllow tile sizes to be non-pow2."

IMPORTANT NOTE! this has an additional fix for nearest_filter that is missing from master!
