Garret Rieger 71c23c1c07 [subset] don't copy the entire global/loca subr lists from the accelerator. 
Instead run a closure on the retained charstrings and copy only the referenced subrs. This significantly speeds up cases with small character sets.

Garret Rieger 4ff09274a8 [subset] In CFF accelerator keep a reference to original face. 
The charstring objects reference memory from the original face so we need to maintain a reference to prevent it from being destroyed.
