DXViewDefaultSystemAdapterChanged Event

DefaultSystemAdapterChanged event is triggered when the default system adapter (the primary system GPU) is changed. This means that it is not longer possible to share a DXEngine's texture with WPF. DXEngine will need to switch to WritableBitmap that is much slower than shared texture because the rendered scene needs to be copied from GPU memory to to CPU memory. In this case it is recommended to save the current scene, dispose the DXViewportView and create a new DXViewportView that will use the new graphics card.
