Comment # 9 on bug 1231065 from Stefan Hundhammer

Also, please name some use cases for a chromium-headless package.

I know that Mozilla once had a 'xulrunner' that used 'libxul' as the common
part between Firefox and Thunderbird, but this fell out of use these days; both
Firefox and Thunderbird come with their own (!) libxul
(/usr/lib64/firefox/libxul.so and /usr/lib64/thunderbird/libxul.so). The hope
to be able to reuse the same lib for both never materialized, let alone
third-party applications making use of it.
