/**
* yields a closure of the supplied parameters, producing a function that takes
* no arguments and is suitable for use as an autogravity function like so:
*
* @param margin (int) - distance from the viewable region edge that an
* element should be before setting its tooltip's gravity to be away
* from that edge.
* @param prefer (string, e.g. 'n', 'sw', 'w') - the direction to prefer
* if there are no viewable region edges effecting the tooltip's
* gravity. It will try to vary from this minimally, for example,
* if 'sw' is preferred and an element is near the right viewable
* region edge, but not the top edge, it will set the gravity for
* that element's tooltip to be 'se', preserving the southern
* component.
