36  * This class has protected constuctor, thus it cannot be created by users. Use COpenGLScene::createViewport instead.
37  * A viewport has these "operation modes":
38  * - Normal (default): It renders the contained objects.
39  * - Cloned: It clones the objects from another viewport. See \a setCloneView()
40  * - Image mode: It renders an image (e.g. from a video stream) efficiently using a textued quad. See \a setImageView().
41  *
42  * In any case, the viewport can be resized to only fit a part of the entire parent viewport.
43  * There will be always at least one viewport in a COpenGLScene named "main".
44  *
45  * This class can be observed (see mrpt::utils::CObserver) for the following events (see mrpt::utils::mrptEvent):
46  * - mrpt::opengl::mrptEventGLPreRender
47  * - mrpt::opengl::mrptEventGLPostRender
48  *
49  * Two directional light sources at infinity are created by default, with directions (-1,-1,-1) and (1,2,1), respectively.
50  * All OpenGL properties of light sources are accesible via the methods: setNumberOfLights(), lightsClearAll(), addLight(), and getLight().
51  * Please, refer to mrpt::opengl::CLight and the standard OpenGL documentation for the meaning of all light properties.
52  *
