c539afb08b [CFF] Use NNOffsetTo<> instead of OffsetTo<> 
I'm pretty sure that's what is intended.

ad28f973f3 Rename offset types to be explicit about their size 
Add Offset16To<>, Offset24To<>, and Offset32To<> for most use-cases.

cab9d5a57d hb-config: Include config-override earlier 
Currently config-override.h is included at the end of this file. This caused a problem for me while undefing HB_DISABLE_DEPRECATED, namely HB_IF_NOT_DEPRECATED was defined before actual undef took place and broke the whole build. I believe it would break builds for some other defines, too. Moving config-override.h include right after predefined configs is more sane and fixes all potential problems with includes.

b5e4032392 -Wno-unused-result 
GCC doesn't let one turn off the warning using "(void) foo()".
People have introduced macros that do "unused << foo()" instead.
Until we do something similar, silence gcc.

Clang on the other hand understands "(void) foo()".

29708e959a [aat] Fix offsetToIndex math for out-of-bounds values 
Previously, some bad font data was accidentally being interpretted as
legit if it happened to not fall out of memory bounds. The intention
of the code was what this commit does.  I'm surprised we weren't getting
a "arithmetic between signed and unsigned values" warning / error
before.

b14475d2ae [subset] further changes to serializer error handling. 
- Rename enum type and enum members.
- in_errors() now returns true for any error having been set. hb-subset now looks for offset overflow only errors to divert to repacker.
- Added INT_OVERFLOW and ARRAY_OVERFLOW enum values.
