[Devel] [Patch] Add control_data for CFF font(type2)

[ha shao]

Attached patch adds control_data to CFF GlyphSlot. It is not
as simple to add similar information for CID-keyed fonts since
charstrings is not actually load in memory here. For CID-keyed
fonts, charstrings is only fetched when needed and then 
deleted. It might be better to use the CFF's charstrings
routine, i.e. load on demand as shown in t2load.c.

Maybe this fetch and delete behavior is intentional for CID keyed
font. well...
