Getting the click position in a string

I am trying to fix mouse.el so that it can heed follow-link properties
in display strings.  But it does not appear that the mouse click info
gives the requisite position information: there is posn-string, and
there is posn-point, but it does not look like there is
posn-string-pos or whatever else which would be able to pinpoint the
actual position within a string that is used as a display property or
before-string or after-string.

Consequently, one can't fetch the text property at the position of the
click in such a string.

Am I wrong here?
