Example application demonstrating the issue

We are seeing the following exception: "pbuffer creation error: Couldn't find a suitable pixel format" when enabling supersampling with an offscreen buffer. We do not see the problem using JOGL1.

The sample works on CentOS 5.4 x86_64; seems like this may be Windows-only.
Comment 4 Wade Walker 2011-01-25 18:15:24 CET 
Confirmed bug on Windows XP 32-bit, Java 1.6.0_23-b05, nvidia GeForce FX 5200, driver 6.14.11.7519.

I created a unit test for this issue and submitted it as a pull request at https://github.com/sgothel/jogl/pull/21.

I also tested this with JOGL 1.1.1a and confirmed that it works that way.

    Fix bug #461 on NV/Win (caps selection)
    
    Allows TestBug461OffscreenSupersamplingSwingAWT to pass on NV/Win7.
    Root cause was using the requested unfixed caps (onscreen, !pbuffer)
    instead of the fixed ones.
