29 * Class that combines a Scene2D with a canvas where to draw the | |
30 * scene. A call to "Refresh()" will update the content of the | |
31 * canvas. A "IViewport" can possibly be accessed from several | |
32 * threads depending on the rendering back-end (e.g. in SDL or Qt): | |
33 * The "ILock" subclass implements the locking mechanism to modify | |
34 * the content of the scene. | |
35 * | |
36 * NB: The lock must be a "recursive_mutex", as the viewport | |
37 * controller can lock it a second time (TODO - Why so?). | |
