The line width override applied to the referenced transition.
Setting the value to 0 removes the width override on the transition.
Setting a new value overwrites any existing width override for that transition.
On a state-to-state transition, this property sets the width of the transition's wire and of the border
of its arrow. On a self transition, this property sets the width of the transition arrow's border.
Getting or setting this property has no effect, and getting it returns 0f, when the
TransitionReference has no associated TransitionReference.Context, such as when it is default.
Throws ObjectDisposedException when you access this property after you call Context.Dispose on the context.
Override the line width of a transition so it appears thicker than the default thickness.
TransitionReference transitionRef = context.GetTransitionReference(transitionID); transitionRef.WidthOverride = 4f;
