basic context shaping is in place now.  (1.2-rc1)

I have patches submitted to do mandatory ligatures via the fonts GSUB tables.
Need to implement fallbacks for fonts that do not have 'rlig' features, maybe
using the 'liga' feature or even falling back to tables to get the 'lam alef'
ligatures correct.

Then basic required arabic shaping will be implemented.
