I'm not familiar with Sword's filters. Can someone give a quick 
overview? When the Sword API reads text, does it filter it from its 
internal format (e.g. ThML, GBF) into a consistent one (e.g. OSIS)? or 
is it more than one? If so which? And then render that into the delivery 
image?

I see lots of possibilities for this:
Simple comparator display in three columns, the outer two columns are 
the different translations, the middle one is the marked differences.
A module quality tool that compares two editions of the same bible and 
only lists the differences.

I think it would be good to have it be an api feature of Sword. What's 
the possibility of getting it into the Sword API? (I know we are all 
busy and I am not a C++ coder anymore. It's been too long.)
