[PD] pd-extended box colors semi transparent

[marius schebella]

hi hans,
does tcl/tk support transperency? is it possible to make the 
backgroundcolor of the objectboxes semitransparent?
esp. in a case like this:

[bang]
  |
[bang]
  |
[bang]

you cannot tell if the middle bang is connected or not. also sometimes 
you could hide parts of objects, and I would rather like to have a 
transparent behaviour.
marius.
