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.
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.
