  x11: Use glXChooseFBConfig when available in X11_GL_GetVisual
  
  When choosing an X11 Visual for a window based on its GLX capabilities, first
  try glXChooseFBConfig (if available) before falling back to glXChooseVisual.
  This normally does not make a difference because most GLX drivers create a
  Visual for every GLXFBConfig, exposing all of the same capabilities.
  
  For GLX render offload configurations (also know as "PRIME") where one GPU is
  providing GLX rendering support for windows on an X screen running on a
  different GPU, the GPU doing the offloading needs to use the Visuals that were
  created by the host GPU's driver rather than being able to add its own. This
  means that there may be fewer Visuals available for all of the GLXFBConfigs the
  guest driver wants to expose. In order to handle that situation, the NVIDIA GLX
  driver creates many GLXFBConfigs that map to the same Visual when running in a
  render offload configuration.
  
  This can result in a glXChooseVisual request failing to find a supported Visual
  when there is a GLXFBConfig for that configuration that would have worked. For
  example, when the game "Unnamed SDVX Clone" [1] tries to create a configuration
  with multisample, glXChooseVisual fails because the Visual assigned to the
  multisample GLXFBConfigs is shared with the GLXFBConfigs without multisample.
  
  Avoid this problem by using glXChooseFBConfig, when available, to find a
  GLXFBConfig with the requested capabilities and then using
  glXGetVisualFromFBConfig to find the corresponding X11 Visual. This allows the
  game to run, although it doesn't make me any better at actually playing it...
