Limited Support for Multiple Top-Level Windows

OpenGL and Qt Quick 2 applications can only have one full screen window existing at a time. Trying to create another OpenGL window, or trying to mix an OpenGL window with a raster one will display an error message and abort the application.

Note: Raster windows (software rendered content based on QWidget or QPainter) do not have this limitation.

Available under certain Qt licenses.
