I have some code around that I started to do regression testing
on the Indic shapers, using the FT2 backend (or did I port it to

You write an XML file that specifies:

 - The font (with an URL) to test with
 - a set of test strings

and then it compares the output with a reference file. It turns
off hinting to reduce the dependence on the font engine.

It certainly won't work cross-backend, and I can't imagine that
anything would. I'll see if I can dig up the code this evening
and post it.
