calculating max vscroll

[Chris Sheffield]

Does anyone have a function that will calculate the maximum amount a  
field can scroll if its height is too small to display it's entire  
contents at once?  (did that make sense; it's been a long day and I  
have a headache :-))

Problem is I have a couple fields that I'm scrolling together, and  
for some reason one is scrolling slightly more than the other, which  
makes things slightly misaligned.  The main field contains regular  
text (this is the one that scrolls slightly more for some reason),  
and the other field contains bullets that should line up with the  
text in the main field (much like the breakpoint list toggle column  
in the Rev script editor).  I thought if I could calculate the  
maximum vscroll, I should be able to limit them so they stay together  
exactly.  But unfortunately I'm having a hard time figuring out how  
to do that.  Both fields are set to use the same font and size and  
have the same textHeight value.

Thanks for the help,
Chris
