                   this solves the mysterious click-and-drag-doesnt-work
                   problem. it was because the window gets focused and stuff

                   dont really know why it should care but it does and it makes
                   a difference.

                   however this very bogus ! !
                   we want to send the button press to the window BEFORE
                   we do the action because the action might move the windows
                   (eg change desktops) and then the button press ends up on
                   the completely wrong window !
                   so, this is just for that bug, and it will only NOT queue it
                   if it is a focusing action that can be used with the mouse
                   pointer. ugh.

                   also with the menus, there is a race going on. if the
                   desktop wants to pop up a menu, and we do to, we send them
                   the button before we pop up the menu, so they pop up their
                   menu first. but not always. if we pop up our menu before
                   sending them the button press, then the result is
                   deterministic. yay.
