Filter is used for things that are transparent, like colored glasses or
plastics. Transmit is used for things that have lots of small holes,
like silk or nylon fabric.
MegaPOV handles them that way in layered textures; the official version
treats them both as transmit (IIRC). Both versions do the right thing
in most cases; it's just the layered textures case that's different.
