Yes, the hardware extension is disabled on Radeon,
but it doesn't negate the fact that OSG rescales the image on Mac OS X
properly, does it? :-p

IIRC, iMac/7300GT uses FX driver, but this doesn't match on Mac with 7300GT
since its renderer name is "NVIDIA GeForce 7300 GT OpenGL Engine."
I don't know if the hardware extension properly works on iMac/nVidia, though.
I'm also curious if this extension actually works with Radeon on my MacBook Pro.
Will try it later.
