'''Write mapping of graphite names to new graphite names based on:
|
|
- an original ttf font
|
|
- the gdl file produced by makeGdl when original font was produced
|
|
- a csv mapping glyph names used in original ttf to those in the new font
|
|
- pysilfont's gdl library - so assumes pysilfonts makeGdl will be used with new font'''
