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.
