-//   OnMouseEntered() -> invoke Show().
-//   OnMouseMoved()   -> invoke SetLocation().
-//   OnMouseExited()  -> invoke Hide().
-//   OnPaint()        -> if ShouldDraw() returns true invoke Draw().
-// Internally GlowHoverController uses an animation to animate the glow and
-// invokes SchedulePaint() back on the View as necessary.
