split OutputDevice from Window

as part of a longer-term goal of doing our
widget rendering only inside a top-level render-
context.

I moved all of the OutputDevice-related code that existed in vcl::Window
into a new subclass of OutputDevice called WindowOutputDevice.

Notes for further work

(*) not sure why we are getting an 1x1 surface in
SvpSalGraphics::releaseCairoContext, but to fix it I clamp
the size there

(*) might have to dump VCLXDevice, and move it's code down into VCLXWindow and VCLXVirtualDevice

(*) can we remove use of VCLXDevice in other places, in favour of just talking to the VCL code?
