	Because your wall is already white and emission media works by
adding the color of the media to whatever is behind. When pov tries
to add the color of the media to the white of the walls it stays white.

	Here's a picture showing this effect:

	The easiest way to get around this is to use megapov 0.7 which
includes a new type of emission media that fixes the problem. Here's
the result with this patch:

	Or if you want to stick with official pov, you will have to combine
an absorbing media along with the emission and get this result:
