[ft] Can I send/receive FT_*Rec structs via network or RPC?

[Crend King]

Hello friends. Recently I'm trying to build a server hosting the 
FreeType library and cache objects, and clients which request the 
rendered character bitmaps from the server. The advantage of doing this 
is the cache in the server is highly shared and reused, and the clients 
are only in charge of implementing the system-specific text out 
procedures. The problem is, sending/receiving the data via network or 
RPC or pipes requires marshaling or serialization. Since there are so 
many embedded pointers in the FT_*Rec structs, and some of them even 
have private members, how do I fully serializing them? Not only do I 
need the final FT_Bitmap, but also I need many metrics and flags stored 
in FT_Face and FT_Size, etc.

One way to solve this problem is to wrap every client-needed field into 
a RPC function, or network request. When the client implementation gets 
more and more complicated, the RPC interface may become messy, and the 
network protocol would be difficult to maintain. Is there any routine 
way to achieve this? I'm really new to FreeType and IPC. Any help is 
appreciated. Thanks!!
