3 stances of a gauge?
 

When you make graphics for a gauge, its usually just one empty and a full stance.
Is it possible to modify the xml-code to make an additional graphic show when the gauge is moving?
Example:
X has full mana and casts a spell which takes 100 mana, would it be possible to show a graphic for a split second with the value of full mana minus 100 mana and afterwards the total amount of mana?
