* @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
|
|
