Remarks

When LineDisplayCapabilities.SupportedWindows is greater than 0 this method can be called to create a new LineDisplayWindow object representing a new window for the device. The new window is not automatically set as the current window when it is created, to set that window as current set the LineDisplayAttributes.CurrentWindow property to point to this LineDisplayWindow object, or on that same LineDisplayWindow object call its TryRefreshAsync method.

Calling this method when LineDisplayCapabilities.SupportedWindows is 0 will result in an exception.

The window size must be at least as large as the viewport size, and it may be larger than its viewport in at most one direction. When LineDisplayCapabilities.IsVerticalMarqueeSupported is True, the window may be larger than the viewport in the vertical dimension. When LineDisplayCapabilities.IsHorizontalMarqueeSupported is True, the window may be larger than the viewport in the horizontal dimension.
