Find the scroll location in wrapped field

[Michael Doub]

Life is good when you have fixed line heights, dontwrap or listbehavior 
and you don't use spacebefore, spaceafter or imageSource

As you might expect, I live in opposite world: with multiple fonts, text 
sixes, spacebefore, spaceafter, word wrap and imageSource.   (I am 
trying to build a special purpose e-Book where the user can shrink and 
expand the text as needed with everything scaling, looking really nice 
with fluid page turning.)

pageranges, and formattedheight not working are forcing me to work a lot 
harder than I would like, because I am not willing to compromise on how 
it looks.
