wgl: wglChooosePixelFormatARB returns the total number of matching
pixelformats and not the number of pixelformats stored in the buffer.

This didn't work due to bugs in wglChoosePixelFormatARB but also due
    to strange behavior of glXChooseFBConfig. Some of its default values
    are not zero or GLX_DONT_CARE which cause some formats not to appear.

As you showed on irc, the error is wglShareLists. The previous patch was
correct. The thing is that now it just selects a different pixel format for the
pbuffer and the main window. wglShareLists is buggy and needs to be rewritten
but that is tricky..

This is the same as bug 11436. The issue is very hard to fix properly as
glXCopyContext which is needed to fix wglShareLists is not supported well in
most drivers. On nvidia's drivers I get a segmentation fault, DRI drivers only
support it for indirect rendering. In other words we need to write our own
CopyContext function by dumping all states :(
