tdf#127316 ooxml/ww8export: DFLT_ESC_*_AUTO - use better formulas
See tdf#99602 and tdf#120412 for many fixes related to escapement.
The poor formulas for AUTO style came to light in 6.3.0.1
with 6.4 commit 32262b0a537207832d7d126d8427d8949b9e821d
Looking at sw/source/core/txtnode/swfont.cxx, we can see in
CalcEsc() that for superscript the DFLT_ESC_SUPER_AUTO
is calculated as the difference between the two ascents.
Because the superscript is smaller, it has a smaller ascent,
so to reach the same ascent line as the original, we can
raise its baseline by fontAscent(fA) - superscriptAscent(ssA).
Since the ascent is approximately 80% of the total fontheight(fH),
we can calculate the Esc number (percentage * 100) as:
EscHeight = fA - ssA (formula in CalcEsc)
ssA = nProp/100 * fA (superscript ascent/height reduced by nProp)
.8 = fA/fHeight (improvement would be to query font.GetAscent)
Esc% = EscHeight / fHeight
Esc% = (fA - nProp/100*fA) / fHeight
Esc% = (1 - nProp/100)*fA/fHeight
Esc = (100 - nProp) * 0.8
DFLT_ESC_SUB_AUTO subscript is similar with the descent(fD)
being the remainding 20% of the fontHeight.
EscHeight = fD - ssD (formula in CalcEsc)
ssD = nProp/100 * fD (by definition of the function of nProp)
.2 = fD/fHeight (an approximation - each font will be different)
Esc% = (fD - nProp/100*fD) / fHeight
Esc% = (1 - nProp/100)*fD/fHeight
Esc = (100 - nProp) * 0.2 (in the negative direction)
For RTF, I can see no reason for the ++nProp except
to try and avoid nProp == 0. It is only .01% after all...
