Detect full-screen and act appropriately about growl HOT 8 OPEN

Comment from Peter:

It appears to be possible to detect at least some full-screen sessions:

nce.html#//apple_ref/doc/c_ref/kEventAppSystemUIModeChanged

As for detecting display captures, that's harder. We could poll every minute or 
so. Another would be to create 
a CGDisplayReconfigurationCallBack; an app that captures a display is likely to 
also change the display's mode 
(particularly its resolution)

CGDisplay apis are deprecated apis starting with 10.6, CGDisplayIsCaptured() 
exists in any event, so really the 
hard case is when the app creates full screen windows and puts them onto a 
particular window level.... are we 
accepting SPI usage for this ticket?

er, i should say the CGDisplay apis for capturing the display are deprecated 
starting in 10.6, they'll still work but 
the recommended by apple solution is to create a full screen window on a 
particular window level and scale your 
content as necessary in the OGL context.

We for sure shouldn't use something that's being deprecated. Can we detect what 
Apple recommends (i.e. the 
full screen window)?

This has been an often requested feature. If you were going to do this, how 
would you 
do this Rudy?

Moving to 2.0.

This seems kind of in line with what you want to do.
