----------------------------------------

[~jahewson] Thanks for the hint. All classes around TextLayout, GlyphVector etc look very
promising as a base for us. Unfortunately we had a number of issues in the past using PDF
fonts as awt.Font objects which was one of the reasons for rewriting a lot of the font related
stuff which you did. Would you see a chance that this no longer happens?

> 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.
