The new approach is to delay kAnimate briefly (with an 68ms timeout) while there is a zero-tick PalVary running, so that it has time to trigger. The previous workaround would immediately process a zero-tick PalVaryInit/PalVaryReverse. This caused problems in QfG3 (bug #10304) where it interfered with PalVaryPause. The previous workaround could also be modified to handle pause/resume, but this new approach should be closer to SSCI's behaviour, which used a timer for a zero-tick PalVary too. This fixes bug #10304, and keeps #5298 fixed too.
