The previous name was clashing with harfbuzz.old.  There are systems
that need to link both...

Clash-free now again.

If you say:

  hb-shape font.ttf text --output-file out.txt

This was previously failing:

  Unknown output format `txt'; supported formats are: TEXT / JSON

Now we simply fallback to TEXT if no explicit format was requested.

Two output formats for now: TEXT, and JSON.  For example:

  hb-shape --output-format=json

Deserialization API is added, but not implemented yet.

Use with Arabic, for example, to see the effect on joining.

This reorders glyphs within the cluster to a nominal order.  This should
have no visible effect on the output, but helps with testing, for
getting the same hb-shape output for visually-equal glyphs for each
cluster.

Just turns all --show-* options on.

Computes all the glyphs that may be generated given a font and
set of Unicode characters.

The order of the Unicode characters is irrelevant.

Sample output:

behdad:util 0$ ./hb-ot-shape-closure Doulos\ SIL\ Regular.ttf f
f f_f

behdad:util 0$ ./hb-ot-shape-closure Doulos\ SIL\ Regular.ttf i
i

behdad:util 0$ ./hb-ot-shape-closure Doulos\ SIL\ Regular.ttf fi

One less argument to type in typical testing workflow!

Most common usecase of hb-view is to test rendering of short words for
testing / inspection.  Not having to type "--font-size 150" each time
isn't such a bad idea...

Also fix cairo cluster generation.

For some reason it doesn't quite work with IranianNastaliq, but
that looks like a font issue.

Also remove shaper_options argument to hb_shape_full().  That was
unused and for "future".  Let it go.

More shaper API coming in preparation for plan/planned API.

This means the --features indices also refer to char position
instead of byte position now.  Same for cluster values reported
by hb-shape.

Will add an option for byte indices later.

Ok, much more useful as a test suite driver now.

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

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

Like hb-view, but prints out buffer contents.

The output format is kinda cryptic.  Suggestions welcome.

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...
