vcl quartz: cache per-run glyphs information

Desktop / LibreOffice - Norbert Thiebaud [gmail.com] - 9 April 2014 11:33 UTC

GetNextGlyphs could only deal with 1 glyph at the time and was recalculing a lot of thing while iterating on the glyphs

This is not just a performance issue.. the notiong of keeping per run glyphs information will be useful to re-establish the proper support of glyphs display positionning by SetDXArray() which today is completely ignored, in favor or letting CoreText spread the extra free space itself.
