UIButton and UIButtonScale behave differently

[UndeadMatt]

When you hold and drag off a button, the UIButton color tweens as soon as the cursor is off the button.  The UIButtonScale does not tween until the mouse button is released.

• create UIButton
  
• make sure Pressed color is different than Normal color
  
• add UI Button Scale
  
• assign the button
  
• add a noticeable scale
  
• hit play
  
• click and hold on the button
  
• with the mouse held, drag off the button.  Notice how the color returns to its Normal state, but the scale remains pressed.

Yup, that's because the button scale script doesn't handle OnDragOver / OnDragOut events, while the button color script does.
