The main motivation here is to have the resource system clean up the
DRI2 drawable automatically so glx doesn't have to. Right now, the
glx drawable resource must be destroyed before the X drawable, so that
calling DRI2DestroyDrawable doesn't crash. By making the DRI2
drawable a resource, GLX doesn't have to worry about that and the
resource destruction order becomes irrelevant.
