 432  * Pros:
 433  *   More responsive OSD
 434  *   Cuts 5% constant CPU usage
 435  *   Seems to have tickled the GFX corruption bug, might make it easier to find that
 436  *
 437  * Cons:
 438  *   There's a comment about video tearing if render is called too often.
 439  *     Will tearing show up in on-demand mode?
 440  *   Moves away from conventional FPS type render loop. VOMP doesn't use 3D GFX / animations
 441  *     currently, so this doesn't matter at the moment?
 442  *   Code needs updating to call doRender,
 443  *   e.g. backing out of the options screen doesn't redraw VWelcome, fixed now
 444  *
 445  *   Maybe have a hybrid system. One that normally works on-demand but can
