Rework of gsview printing with addition of new Print control dialog
This adds an additional project (gsprint.vxcproj) which will do the necessary native
calls to bring up the custom print dialog for the output device.
We can then obtain the settings and make the appropriate page
size adjustments in creating our xps content.
