Aaarg. Maybe it would be most useful to disable the handling of the
awt.headless property for now and reenable it when the headless toolkit
and stuff is sorted out completely. The challenge is basically, that we
want to use the 'normal' freetype/cairo stuff when available and use the
java only impl only when that's not the case (i.e. somebody compiled a
stripped down classpath without any outside GUIish dependencies). Maybe
the best solution would be to use the GTK toolkit even for awt.headless
== true, when that's available, and throw a HeadlessException in all the
toolkit methods when that property is set.
