Hi.  I'm trying to fill areas with patterns and then overlap the patterns
without losing sight of the patterns that are underneath.  The fill operator 
treats white space as opaque.  I'd like to fill an area and have white treated
as clear.  Is there any simple way to do this?

This is what       \\\\\\\\\\       //////////       XXXXXXXXXX
I mean...          \\\\\\\\\\   +   //////////   =   XXXXXXXXXX
                   \\\\\\\\\\       //////////       XXXXXXXXXX

not this -->                                         \\\\\/////
                                                     \\\\\/////
                                                     \\\\\/////
Thanks,
fran
