That's essentially what Ben was proposing, except (AIUI) by using
an enum for the type of effect, and falling back to venetian blinds
if the transparency didn't work.

Perhaps we should just do this then. I will take a look at the patch.

Thanks. I'll take a look at that too.

A bit snowed under with other things today, so might not be for a bit...
