 476  * OSDOVG-ROD-EXPERIMENT
 477  *
 478  * To switch OsdOpenVG to render-on-demand instead of rendering in a loop
 479  *
 480  * Pros:
 481  *   More responsive OSD
 482  *   Cuts 5% constant CPU usage
 483  *   Seems to have tickled the GFX corruption bug, might make it easier to find that - update: found and fixed!!
 484  *
 485  * Cons:
 486  *   There's a comment about video tearing if render is called too often.
 487  *     Will tearing show up in on-demand mode?
 488  *   Moves away from conventional FPS type render loop. VOMP doesn't use 3D GFX / animations
 489  *     currently, so this doesn't matter at the moment?
 490  *   Code needs updating to call doRender,
 491  *   e.g. backing out of the options screen doesn't redraw VWelcome, fixed now
 492  *
 493  *   Maybe have a hybrid system. One that normally works on-demand but can
 494  *   also switch to looping on the fly if necessary.
