New Revision: 2313
URL: http://svn.gnome.org/viewvc/tomboy?rev=2313&view=rev

Log:
* po/POTFILES.in:
* Tomboy/Addins/PrintNotes/Makefile.am:
* Tomboy/Addins/PrintNotes/gedit-print.h:
* Tomboy/Addins/PrintNotes/gedit-print.c:
* Tomboy/Addins/PrintNotes/gtksourceprintjob.h:
* Tomboy/Addins/PrintNotes/gtksourceprintjob.c: Delete old
  libgnomeprint-dependent print code. Add Mono.Cairo reference.

* Tomboy/Addins/PrintNotes/PrintNotes.addin.xml: Bump to version 0.2.

* Tomboy/Addins/PrintNotes/PrintNotesNoteAddin.cs: New printing
  implementation using Gtk.Print. Partial fix for bug #512369. There
  are known wacky margin/header/footer problems on Linux. Many thanks
  to Benjamin Podszun for doing this in record time.
