/* These calls set the display system that will be associated

* CreateDXGIFactory1 by the current thread.
*
* Existing factories and DXGI objects created from them are
* not affected.
*
* Gallium DXGI has both per-thread and per-process settings.
* If the per-thread display system has been set (i.e. a function
* of these was called, and the last one called was not UseNothing),
* it will be used.
* Otherwise, the per-process display system will be used if set, or
* and other the factory creation call may either fail, or use an
* user-specified default..
*
* The per-process setting can be altered by calling
* GalliumDXGIMakeDefault, which will set the per-process setting
* according to the current per-thread setting.
*
* GalliumDXGIUseNothing() is the initial state, which means that
* the per-process default should be used, and if that is "use nothing"
* too, the call will either fail or use a user-specified default.
*
* NOTE that setting the per-process default is NOT atomic and must
* not be done concurrently with other calls to GalliumDXGIMakeDefault,
* CreateDXGIFactory or CreateDXGIFactory1.
*
* The PFNHWNDRESOLVER function is passed HWNDs coming from
* the API user and must return window-system-specific values:
* - X11: Window*
* - GDI: HWND
