   Actually, given that we now have a pixel-accurate position within the

   displayed object in the first place so that one can calculate the
   relative position in the image easily, too.

it is difficult to generalize this to text because the same text can be
presented differently depending on font, overlays, display properties
and probably many other influences i can't think of at the moment.  a
specific query (mouse click) can yield a specific answer but such info
is not inherently in the text (anymore).  w/ images it's easy of course.

this is the problem i'm mulling wrt determining what is the right thing
to do in order to support a fractional return value for the function
