A couple notes on Apple's X11 Freetype build:

* Strangely, Apple doesn't build Freetype with a few Apple-specific  
options (ftoption.h):

- TT_CONFIG_OPTION_BYTECODE_INTERPRETER - to use the TT hinting.  As  
the ftoptions.h note says for this, the hinting (code?) is patented.   
I take the (very possibly naive) view in my framework that since we  
Mac users are using this in OSX, we can use this.  If others know  
better, I can always remove this from my framework builds (maybe the  
FT auto-hinter works well enough).

- TT_CONFIG_OPTION_COMPONENT_OFFSET_SCALED - affects composite glyphs,  
the option is a matter or how Apple vs MS defines offsets.  So why  
does Apple not build FT with Apple offsets?!


There are some issues in the OSX 10.4 X11 Freetype handling Mac  
suitcase-packaged fonts, and I think a couple font package formats  
were left out (dfont?).  They are probably fixed in Leopard's X11 FT,  
since it uses FT 2.3.5.  But this leaves a disparity between Tiger and  
Leopard as to what is supported.
