* cairo/cairo-api.xml: add the Content enum type and fix surface symbol. * gdk/gdk-sharp.dll.config.in: s/3.0/3/ on the so name. * sample/Makefile.am: enable scribble.exe build * sample/Scribble.cs: rewrite for new API, specifically replace pixmap drawing usage with cairo, and use OnDrawn in place of OnExposeEvent. Also Made it a subclass of DrawingArea instead of handling events.
