Solution for old reports, that ray_transp filtered image textures wrong.
Problem was in calculation of oversampling vectors for correct AA. With
the new AA method, this is less necessary, so the code now doesnt use
mipmapped or filtered images when it is refracted. For reflected rays it
does still use the filter though, there the error is hardly noticable.

For all tests and report .blend files it looks much better.
However, a real mathematical solution is preferable still.
