In future we may need propoper dependencies here. We use reference counts so
this should be easy to implement.

See https://github.com/dvdhrm/kmscon/pull/3 for a discussion of K_OFF in the VT

subsystem has been written.

Similar to libvte we could speed up font-drawing by using cairo_scaled_font_t to
bypass pango entirely if a glyph is already in the hash-table.
