Enumerate All Live Templates (Including User-Defined)

I've been trying to enumerate / locate a user-defined file template and cannot do so.  I've tried using FileTemplatesManagerImpl, StoredTemplatesProvider, LiveTemplatesManager.

I've tried enumerating through QuickListSupports from FileTemplatesManager.  None of these classes will return my user-defined templates.

I also tried exporting the file template and using Template.CreateFromXml().  That doesn't seem to work with the exported template file format.

What am I missing here?
