Specialize the FilterValid routine to not consider the pixels as pixels but rather as values. This seems somewhat inelegant but it's fine in terms of a quick fix.

If the intensity is greater than one, then we're treating it as a float value, so when packing it into a pixel, just pack the value instead of scaling it to 255...
