The DC access will have to be done through GDI, yes, but that can be a
simple wrapper that calls the corresponding driver entry point. For
functions that don't need to access the DC, opengl could call x11drv
directly, though of course if everything goes through GDI it will make
it easier to support opengl with a different driver.
