'''Write mapping of graphite names to new graphite names based on:
|
||
|
|
- two ttf files
|
||
|
|
- the gdl files produced by makeGdl run against those fonts
|
||
|
|
This could be different versions of makeGdl
|
||
|
|
- a csv mapping glyph names used in original ttf to those in the new font '''
