Turn the SoftwareContext plugin into the Scenegraph Software Adaptation

The 2D renderer will now become a built-in adaptation of scenegraph that
should always be available to fallback to when there are no other
renders available.  So rather than be an external plugin, now it is a
built in adaptation.
