| virtual

Hit-testing: returns a flag indicating hit test details, plus information about position.

contextObj is returned to specify what object position is relevant to, since otherwise there's an ambiguity. @ obj might not be a child of contextObj, since we may be referring to the container itself if we have no hit on a child - for example if we click outside an object.

The function puts the position in textPosition if one is found. pt is in logical units (a zero y position is at the beginning of the buffer).
