Hi all,
I've attached a pretty trivial patch which creates Erode and
Dilate menu items. These are basically the vpropagate plug-in
called with default values. This stems from me spending about an
hour looking for this functionality today and not finding it.
Eventually someone told me "Those are the more white/black
functions in value propagate", which seemed a little obscure for
what I reckon are fairly basic functions. So I did this.
People may think it's useless, so I'll mail it here and let
people decide whether it's useless enough to get dumped. :)
Cheers,
Dave.
