libardour is the backend to multiple UIs (not all of them graphical). it
is not allowed to have a dependency on the code used by any particular
UI implementation. i.e. its not OK for the curses implementation to have
to link against GTK, or vice versa.
at some point, we hope to do complete process separation, actually (so
that the code in libardour runs in a completely non-graphical process).
but thats a digression.
