Made the handling of glyphs with holes more robust.
- SimpleGlyph.as now sorts it's contours by size (size of area of bounding box). It assumes that the biggest contour is the one containing other holes, if any are present.
- Contour.as now sorts the holes contained by it by the upper boundary, instead of the right boundary, as this provides more stable results.
- Fixed a problem in CharacterIndexMappingTableParser.as where the last, invalid segment of a segment to delta mapping table was parsed as well, potentially resulting in end of file errors.
- The order in which Horizontal Header and Horizontal Metrics tables should be parsed by OpenTypeParser.as has been defined.
