This method's first result is @scheme[#f] when the mouse
event does not correspond to a location in the editor.
If the first result is an @scheme[text%] object, then the
second result will be a position in the editor and
otherwise the second result will be @scheme[#f].
If the second result is a @scheme[text%] object, then the
first result will be a position in the editor and
otherwise the first result will be @scheme[#f].
The @scheme[editor<%>] object will always be the nearest
enclosing editor containing the mouse click.
