* Remove the manual OSA method but rather pass on derivatives to the textures. This means that at the moment e.g. the bricks node is not antialiased, but that image textures are now using mipmaps. Doing oversampling on the whole nodetree is convenient but it is really the individual textures that can do filtering best and quickest. * Image textures in a texture node tree were not color corrected and did not support 2d mapping, now it's passing along shadeinput to make this possible. Would like to avoid this but not sure how. * Fix preview not filling in all pixels when scaling or rotating in the texture nodes.
