* 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.
* configure.in.in: Detect GDK backend.
* */*.dll.config.in: Link against the libs of the correct GDK backend
instead of using x11 on Linux/win32 on Windows.
