OverlaySurfaceHost Class

OverlayHost is a control that is used to show the 3D scene when the OverlayTexture is used for the PresentationType property. The control is derived from System.Windows.Interop.HwndHost and provides a windows handle based area that can be used to display the 3D scene with using the Vulkan SwapChain. The area occupied with OverlayHost cannot be used by any other WPF element (this is possible when using SharedTexture PresentationType).
