postscript doesn't support the alpha channel and there is nothing
matplotlib can do about it. It's a postscript limitation. Right now
the only vector output that supports alpha is SVG. Hopefully we'll
get a PDF backend one day which also supports alpha.

True. Just had to check this again to make sure, but even PS3 does not support
Alpha transparency in any way. The big improvement there was bitmapped
masking of images, but the whole concept of true transparency really seems to
be an extremely new idea.
