This partially backs out the previous patch. We no longer need to set/get anything in the nsIPrintOptions.

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
