Issue Type: DEFECT
Summary: Invalid parse of GSUB of OpenType font
Product: General

Hardware: All
OS: All

Picture with wrong punctuation glyphs
In Japanese vertical text writting on Writer document,
some glyphs are not replaced for vertical writting by GSUB table even with
OpenType font having GSUB table.
This is because the parse of the GSUB table in the font is invalid.
In FreetypeServerFont::ApplyGSUB function, FeatureParams entry have to be
ignored
while reading feature table. nCntLookups is wrong without the skipping.
In the attached picture,
- left: AOO 4.1.2, 1st and 4th lines contains wrong punctuation glyphs
- right: with fix, 4th line has been fixed. But 1st line is still the same
because Ume Plus is truetype font and not GSUB provided.
