Comment 10 for bug 648289

Attempted fix "works for me".

Probably not robust in the Pre 2.8.0 WxWidgets versions, as you will still die a horrible death if you call SwapBuffers(); when you don't happen to have a double buffered visual.

The behaviour is strange, and probably WxWidgets fault anyway, as the docs DO state that when specifying no arguments to the GLCanvas constructor you are supposed to get RGBA and DOUBLEBUFFER for free.

Whatever.. (This has to be super-helpful enough anyway, especially coming from a gEDA develoepr ;))
