question: public static String hintingSize ( Font font ) { int instrSize = 0 ; LocaTable locaTable = FontUtils . getLocaTable ( font ) ; GlyphTable glyfTable = FontUtils . getGlyphTable ( font ) ; for ( int i = 0 ; i < locaTable . numGlyphs ( ) ; i ++ ) { Glyph glyph = glyfTable . glyph ( locaTable . glyphOffset ( i ) , locaTable . glyphLength ( i ) ) ; instrSize += glyph . instructionSize ( ) ; } double percentage = instrSize * 100.0 / glyfTable . headerLength ( ) ; return String . format ( "%d bytes (%s%% of glyf table)" , instrSize , twoDecimalPlaces . format ( percentage ) ) ; }
target:  Gets the size of hinting instructions in the glyph table, both in bytes and as a fraction of the glyph table size.
