What Jiri introduced is a way to visualize the two important aspects
that define how large a MBall displays.
1) the inner circle = actual size, based on 'stiffness' parameter
2) the outer circle = maximum size, based on maximum area of influence
The 'size' of a MBall is defined by these two parameters together.
Previously we only were drawing the 'influence' area, which indeed can
be scaled indefinitely. The 'actual size' (stiffness) is maximum the
size of the influence area.
The choice for making the inner and outer circle selectable, and have a
single Scale operation on this I find very correct, clear immediately,
and a real enhancement. Visually the scaling you do really gets
perceived as a scaling anyway, plus it allows to use the Manipulator
for it.
By introducing a new hotkey/tool for it you'll lose the simplicity as
it currently is.
Main disadvantage is that 'stiffness' has no X/Y/Z component, and that
the current axis-only scaling doesn't reflect yet in the drawing of
circles. Just needs some little tweaks...
