I've been struggling to properly re-dimensioning a pane and its child's only to find that setting Pane.PrefHeight or Pane.PrefWidth had no effect or not the effect I expected...
(In one case the layout simply didn't change, on another one, the Form itself changed instead of the pane)
So I thought... "Why not try SetLayoutAnimated, but with duration Zero?"
And so I did.... And the result was... nothing... the layout did not change! However, using one (1) as the duration DOES work!
