I've checked a fix for picture-mouse-set-point into the emacs-23 branch.
The underlying situation is currently somewhat unsatisfactory---the
pixel position of a mouse-event in the text area counts X from the start
of the text area (excluding margins and fringes), and Y from the top of
the window (including the header line).
This arises from some internal redisplay engine semantics, and is not
really intuitive. Rightfully, the header-line should be excluded from
the pixel Y coordinates. It's not feasible to change this for Emacs 23,
since existing code might depend on the current behavior. But we can
contemplate changing this in Emacs 24.
(Such a change will not affect the picture-mouse-set-point fix.)
