Thanks. This is interesting.
It seems that your graphics card doesn't support WGL_ARB_multisample,
but does support WGL_ARB_framebuffer_sRGB, which seems a bit unusual.
I've built an libGL1 with a change to handle this situation better [1]
If you download that, chmod +x it, and replace /usr/bin/cygGL-1.dll with
it (keep a copy of the existing version), you can try 'glxinfo' and
plotting with octave, to see if it improves things.
