                   actions from clicks on client windows are NOT queued.
                   this solves the mysterious click-and-drag-doesnt-work
                   problem. it was because the window gets focused and stuff
                   after the button event has already been passed through. i
                   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 too, 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.

                   XXX further more. focus actions are not queued at all,
                   because if you bind focus->showmenu, the menu will get
                   hidden to do the focusing
