The problem is that one can apply roundRadius, joinStyle and so on in
what we could term a 'global' fashion insofar as they refer to all the 
extremities
on a polygon graphic.

It might not be a bad idea to consider implementing the ability to 
manipulate
corners (e.g. via roundRadius) individually in a future version of Livecode.
