poor performance when part of window sits outside of desktop screen

[Jose Martinez]

Hello,

I been troubleshooting this performance issue that has been plaguing me for weeks.  It turns out that regardless of the size of my Stage, if part of it sits outside of the desktop screen (so that 100% of it is not visible on the desktop) then performance drops considerably.  

The FPS drop from 60 to low 50's but that might be misleading.  Where 50 FPS would be fine (i would imagine), in my case it causes jitterish movement of Node along their PathTransitions.
