 439  * Pros:

 442  *   Seems to have tickled the GFX corruption bug, might make it easier to find that

 444  * Cons:
 445  *   There's a comment about video tearing if render is called too often.
 446  *     Will tearing show up in on-demand mode?
 447  *   Moves away from conventional FPS type render loop. VOMP doesn't use 3D GFX / animations
 448  *     currently, so this doesn't matter at the moment?
 449  *   Code needs updating to call doRender,
 450  *   e.g. backing out of the options screen doesn't redraw VWelcome, fixed now
 451  *
 452  *   Maybe have a hybrid system. One that normally works on-demand but can
