OpenType Indic Support

[Eric Mader <mader jtcsv com>]

Hello,

I've got an OpenType based Indic shaper that I'm working on porting to 
Pango. It's a single piece of code that's driven by a script-specific 
table. Ideally, I'd like to have a single script_shape routine that's 
called with the address of the table as a parameter, but it doesn't look 
like there's any way to do that since the PangoEngine isn't a parameter to 
the script_shape routine, and there's no provision for a client-specific 
data pointer.

So, I'm guessing that the best I can can do is to make a bunch of short 
script_shape routines that call the main routine with the right table 
address. Have I missed something, or is this the best I can do?

Also, I'm a little unclear on what the different types of shapers are. I 
assume that mine should be an "xft" shaper like the Arabic one. Can someone 
give me a pointer for where to look to hook in my new shaper?

Thanks,
