I've been trying out the patch - using quartz debug, since I don't have 
a retina display.
Aside from occasional artifacts in theSwing  controls which may well be 
code there
that doesn't handle this case well, the only  pure 2D thing that I 
noticed was the
Texture Paint demos in Java2Demo don't seem to handle this well. The 
textures
aren't being scaled.

Likely not our problem, rather quartz debug, is that if I switched 
display modes
whilst quartz debug was running *and* we had the 2D animation running, then
large parts of the display flashed, even after I quit the 2D demo. I had 
to quit
quartz debug to get it to stop.

-phil.
