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.
1. If there is any offset (x or y), print out both x and y offsets.
2. Always print out the advance in the major direction of the buffer.
Ie. even for zero-advance glyphs, print a "+0". This is more intuitive.
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.
Computes all the glyphs that may be generated given a font and
set of Unicode characters.
The order of the Unicode characters is irrelevant.

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 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.
