[Bf-committers] Bicubic filtering for bump maps, patch + discussion

[Αντώνης Ρυακιωτάκης]

New version:

Applied Brecht's suggestion and placed the glsl lib header one level
higher. I see that the lib source is also appended to the GPUPass
structure. If so wouldn't it make sense to store the new lib code
there(though it seems to work without doing so)? And if so, shouldn't
we take care of creating the lib string once to avoid lots of
duplicates around? Where is the best place for that? Not yet looked
into loading Luminance images to the bump mapper. It's the most
complicated part, but working on it.
