optionally merge TTX tables found in UFO3 data folder

UFO3 has a ‘data’ folder where one could store extra, application specific data.

http://unifiedfontobject.org/versions/ufo3/data/

I propose that ufo2ft automatically merges into the compiled font any .ttx tables which it finds inside font.ufo/data folder, if the filename starts with the org.fonttools.* reverse domain.

Before I start working on the patch, I wanted to see if people liked the idea.

The immediate use case which I have in mind is merging the private TSI* tables where Microsoft Visual TrueType stores the hinting source data.

Having ufo2ft merge these automatically upon compilation would be handy I think.

What do you guys think?

just to clarify: when i say VTT stores its sources in the “binary” private tables, I just mean that they are stored in the compiled font, I don’t mean they are binary data. It’s actually UTF-8 encoded plain text, containing the VTT Talk and assembly source code.

Should this issue be closed as ‘wontfix’ or left open? 😃
