int32 PhaseCount
The PhaseCount controls how many phases are possible know what to modulus the current frame count by to determine if this is the current frame to draw the widget on.
If the Phase is 0, and the PhaseCount is 1, the widget will be drawn fresh every frame. If the Phase were 0, and the PhaseCount were 2, this retainer would draw a fresh frame every other frame. So in a 60Hz game, the UI would render at 30Hz.
