> Implemented proper rendering of Indian languages, which need extensive Glyph substitution. The GSUB table has been read and used effectively to replace some compound words with their respective Glyphs. All tests are passing. I have tested this for the Bengali font. Please review these changes and let me know if it makes sense to incorporate these.
