implementation supports them but we need to correctly map our keyboard input
to the correct cells. Pango depends on glib so we can probably use the glib
functions for UTF-8/Unicode handling.
- Add glyph caching support with cairo_scaled_font_t. The libvte does this
inside vtedraw.c but it is licensed by GPL so we need to rewrite it if we
want it.
This would speed up our font-draw functions considerably as we would bypass
pango if a glyph is already in the hash-table.
