• [ttLib/otTables] Cleaned up virtual GID handling: allow virtual GIDs in Coverage and ClassDef readers; removed unused allowVID argument from TTFont constructor, and requireReal argument in TTFont.getGlyphID method.
  Make TTFont.setGlyphOrder clear reverse glyphOrder map, and assume glyphOrder internal attribute is never modified outside setGlyphOrder; added TTFont.getGlyphNameMany and getGlyphIDMany (#1536, #1654, #2334, #2398).
• [py23] Dropped internal use of fontTools.py23 module to fix deprecation warnings in client code that imports from fontTools (#2232, #2399, #2400).
• [subset] Fix subsetting COLRv1 clip boxes when font is loaded lazily (#2408).
