Yeah, that's the point.  Somehow I did not see a perfect way to solve 
the problem.  One way, is (as you say) to add an "invalid" marking, 
which would of course invalidate all child objects...
Another way is to "define" the intersection point anyway (that is actually
what I did in kgeo), which is much more simple, even if not completely
correct.  The point is if it is nice or not to see parts of the graphics
"disappear" when you move things in an "invalid" position.

Don't know what is best, actually.
