The QWSGLWindowSurface class provides the drawing area for top-level windows with Qt for Embedded Linux on EGL/OpenGL ES.
It also provides the drawing area for QGLWidget whether they are top-level windows or children of another QWidget.
This function is under development and subject to change.
Note that this class is only available in Qt for Embedded Linux and only available if Qt is configured with OpenGL support.
