Is this a known bug in XFixesInvertRegaion

[Derek Wang]

Hi Keith,

The rect defined in XFixesInvertRegion never be used (see the following code) 
and it may cause server do nothing when users invoke XFixesInvertRegion. Is this 
a known bug ?

void
XFixesInvertRegion (Display *dpy, XserverRegion dst,
                     XRectangle *rect, XserverRegion src)
{
     XFixesExtDisplayInfo        *info = XFixesFindDisplay (dpy);
     xXFixesInvertRegionReq      *req;

     XFixesSimpleCheckExtension (dpy, info);
     LockDisplay (dpy);
     GetReq (XFixesInvertRegion, req);
     req->reqType = info->codes->major_opcode;
     req->xfixesReqType = X_XFixesInvertRegion;
     req->source = src;
     req->destination = dst;
     UnlockDisplay (dpy);
     SyncHandle();
}
