Understood, what I ended up with (with the help of Tore) is:

/* Credit goes to Tore Anderson for helping me figure out how to do this
 * better.  And all of the blame now goes to me. */
void myGetGeometry(ObClient *c,
        int *rx, int *ry, unsigned int *rw, unsigned int *rh)
{
    *rx = c->frame->area.x + c->frame->size.left;
    *ry = c->frame->area.y + c->frame->size.top;
    *rw = c->frame->area.width - c->frame->size.left -
c->frame->size.right;
    *rh = c->frame->area.height - c->frame->size.top -
c->frame->size.bottom;
}

This seems to do what I want, and I posted an updated patch. (Bugzilla
#1114)

I am curious what you think of the patch though.

Thanks.
