Re: making an ipelet for changing a straight line into a wave...

Jens,

Sounds like a good idea.  I attach here an ipelet to fill an existing path
with a linear gradient, based on a few points and a line the user has
placed; I think it will provide some examples and guidance that are helpful
for you.  Like your plan, it involves finding the endpoints of an existing
line segment.  I'll be happy to answer any questions if the comments in the
code aren't clear enough!
