GFX now handles non-default adapters

Browse source 
The GFX (DirectX) pipeline did not respect the choice of adapter and
always went for the default one.  Normally this isn't an issue unless
you wish to target a particular adapter and display device combination.
This has been corrected.

The GFX initialize functions now attempt to find the best adapter that
matches a given display device (i.e. monitor) if one has been passed in.
To aid with choosing a display device some new monitor enumeration
methods have been added to the platform window manager.  These methods
have been exposed to the Canvas.
