Version 1.74 runs natively on OS X. Indicators are separated from the style \ 
buffer so there can be more indicators. Wide lines are faster.

The previous commit included the following changes:
Version 1.73 allows style changes to be made during text modification events. 
Version 1.72 is more efficient at handling per-line information. 
Version 1.71 has some internationalisation fixes.
