Not quite sure what you mean, but being able to select a new "colour" 
called 'transparent' as the foreground and/or background colour would be 
fine.  I mainly thought of it as adding a new pre-defined 'transparent' 
colour to the colour selection dialog. (Of course, I have no idea if 
that's a workable solution).

I've filed a bugzilla entry for this as bug 402113.
