Wow, who knew bool is one byte and I was using it as a 4byte int?!

C++ auto casts fails you in mysterious ways...

A diff program written in Python that is more suitable for comparing
hb-shape output from different backends.  Main differences with stock
diff:

1. It outputs one line's comparison at a time, as opposed to batching
'+' lines and '-' lines.

2. It colors the part of the line that changed, taking word boundaries
into consideration.

You can pipe the colored output to 'less -r'.

At least works for cross-compiling now...

Like hb-view, but prints out buffer contents.

The output format is kinda cryptic.  Suggestions welcome.

Bug 40953 - fail compile git: make[2]: *** [hb_view-options.o] Error 1

Fixes bug with uniscribe not handling GIGANTIC sizes.

Make --font-file accept "-" to mean stdin, and have it work
in Windows too!

Apparently there's no equivalent to "/dev/stdout", so write using
stdio to be able to output to stdout.

Now we can use the same code to do other utils...

We now support using -1 for NUL-terminated strings.
