Helper class responsible for creating and managing the GraphicsDevice. All GraphicsDeviceControl instances share the same GraphicsDeviceService, so even though there can be many controls, there will only ever be a single underlying GraphicsDevice. This implements the standard IGraphicsDeviceService interface, which provides notification events for when the device is reset or disposed.
