Comment(by strk):
Oh, the same applies to ST_MapAlgebraFct, the user function should be able
to access all informations related to the pixel.
Geographic location, I'm mostly interested in, but I guess if x/y are also
given maybe we should also pass raster band metadata (pixelsizes, offsets,
rotations).
