 * This needs work to distinguish between XMap's translation from unicode

 * code point is in the font.

 * ie a GlyphMapper ought to be able to say if a code point maps to a glyph

 * IN THIS FONT, not just in this encoding.

 * Because of the current lack of distinction the NativeGlyphMapper and

 * XMap classes could be merged, however its cleaner to make them separate

 * classes so we can build caches for a particular font.
