[osg-submissions] FrameBuffer Antialiasing

[paul1492 at yahoo.com]

I am no expert on this but attached are files to have OSG 1.2 support Antialiasing to a FrameBufferObject. I am sorry that I haven't made the same changes to the SVN code but the coversion for SVN should be straightforward.

The changes I have made are based on NVIDIA's simple_framebuffer_object.cpp example (see attached).

To use it, call:
     cameraNode->attach(COLOR_BUFFER, texture);
     cameraNode->attach(MULTISAMPLE_BUFFER, depthSamples, coverageSamples);

I could have added more error checking on the valid depth and coverage samples (like in the example program) but I didn't.

Feel free to make any changes you like..

Paul P.
