There is a cairo sample in the gtk-sharp module that shows how to draw to a
surface and then paint it to the context.  You don't need a pixbuf to do
that, unless you want some of the additional persistence stuff provided by
the pixbuf API.  Here's a link to the sample in master:

https://github.com/mono/gtk-sharp/blob/master/sample/CairoSample.cs

The cairo stuff is the same using 2.12, but you override the OnExpose VM
instead of OnDrawn, and you need to use Gdk.CairoHelper to get a cairo
context for the Gdk.Window.  The 2.12 version is in the sample place on
gtk-sharp-2-12-branch.
