Find Scroll position of a chunk within a line that is wrapped

[Michael Doub]

A related question to positioning a line within a field, is positioning 
a chunk within a line that is wrapped.   I am stumped on this one and it 
may need engine support.   I don't know how to figure out the scroll 
value of something in the middle of a wrapped line.   In the thread 
discussing scroll positioning within a wrapped field we see how to find 
the top.   I figured out how to get the bottom using James Hales 
approach. (code in the forum and MasterLibrary)

Does anyone see a way to calculate the scroll position of a chunk within 
a line that is wrapped?

Regards
   Mike
