What this does is:
1) Reflows the first time constrained and remembers mOverflowArea.XMost() of
the HTML frame and then later uses that for the calculation of the ratio.
2) Renames some variables
3) This also changes the the maximum STF ratio from 0.5 to 0.3 to match the
dropdown in PP

2) Fixes the negitive page range display problem
3) Improves performance by reducing the delay on pages not in the page range, i.e. before if you printed the 30th page out of 31 you had to wait 15 secs to get to the 30th page to print it.
4) Added AbortDocument, so now when Print jobs are cancelled we call AbortDocument and remove them from the print spooler
5) Fixed a couple of minor issue with Canceling and cancelling mail printings
6) selection was not printing correctly. The problem with selection was that the clip was not being set corrctly.
