Can I open a transparent window using “PsychImaging(‘OpenWindow’,…)”?  
I have an idea to show some visual stimuli when play a video game.  
So I need a transparent window background through which the game screen can be seen.  
I try to use “PsychDebugWindowConfiguration(1,0.5);”， but the stimuli also become transparent.  
Is there any way to achieve it?
