surface_gdi in particular seems to be very ddraw-centric. It uses things like
"ddraw_window" and "ddraw_primary" all over the place. So in the scope of
surface_gdi.c ddraw_primary is more consistent with the overall code. I wonder
though if ddraw_primary is always same as render_targets[0]. If it is, and is
basically some legacy leftover stuff, maybe it would make sense to get rid of
it. It's confusing to have multiple things for same purpose.
