------------------------------------------------------------------
I wonder if I'm missing something...
{{gsubWorkerFactory.getGsubWorker(pdType0Font.getCmapLookup(), gsubData);}} is
still hit for every call of showTextInternal().
Another thing to do: the default behaviour should be the same as 2.0.9 i.e. no
rearrangement. What I'm thinking is some setter in PDPageContentStream that
activates the GSUB worker for that script, e.g. setScript("Bengali").

> 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.
