Always use either glXCreateNewContext or glXCreateContextAttribsARB for GLX
Explicitly create the GLX window for onscreen surfaces.
Use glXCreateContextAttribsARB to create GLX contexts when GLX_ARB_create_context is supported, otherwise use glXCreateNewContext.
This will allow us to explicitly destroy hibernated GLX windows, which will hopefully plug some GPU memory leaks that were causing instability.
