How can I find the full path to a font from its display name on a Mac?
I haven't been able to find anything that does this directly.  I think you'll have to iterate through the various font folders on the system: /System/Library/Fonts, /Library/Fonts, and there can probably be a user-level directory as well ~/Library/Fonts.
I am using the Photoshop's javascript API to find the fonts in a given PSD.
Given a font name returned by the API, I want to find the actual physical font file that font name corresponds to on the disc.
This is all happening in a python program running on OSX so I guess I'm looking for one of:

Some Photoshop javascript
A Python function
An OSX API that I can call from python
