The giorune command is a minimalistic app to investigate the
information an HarfbuzzShaper provides about the graphical
representation of a rune (glyph) using a given font face, size and
metric.
This little project was inspired by the fact that the ui-library
gio didn't typeset the tibetan script properly. I
wanted to figure out if the problem lies with gio or with the
[harfbuzz go-port. An other problem with gio/text was that it seemed pretty hard
respectively not straight forward to freely layout text in a window.
Hence I implemented the library giorune as a replacement of gio/text
which uses only gio's painting capabilities and the
shaping.HarfbuzzShaper to paint a rune's graphical representation. The
giorune command is now an application of the giorune-library testing
its usefulness and visualizing font-metric information about a glyph
provided by shaping.HarfbuzzShaper.
