The flag is telling if the measurement optimization is turned on
If it is, then if CanSkipMeasurement() returns true (because of the explicit sizes)
the component never gets measured
However, when changing the component dimensions from the outside (using Resizable for instance)
we would like to know min/max dimensions to know how much we can contract/expand
Thus we should switch this optimization off for this kind of components
NOTE: true by default
