Summary0030124: Visualization, AIS_InteractiveObject - clean up confusing Presentation invalidation logic
DescriptionAIS_InteractiveObject has several properties related to presentation invalidation:
- RecomputeEveryPrs()/ListOfRecomputeModes()/MustRecomputePrs()/SetRecomputeOk()
- ToBeUpdated()/SetToUpdate()

The usage of first set of methods looks like a nonsense - they are used as temporary flags within modified object while it is modified by methods like AIS_InteractiveContext::SetWidth() so that invalidated modes are recomputed by AIS_InteractiveContext::redisplayPrsRecModes(). At the same time, RecomputeEveryPrs() flag is messed up with the list of invalidated modes. The list of invalidated modes is stored as AIS_InteractiveObject class field regardless of existence of these modes.

The second set looks more clear, since they invalidate already computed presentations and handled by AIS_InteractiveContext::redisplayPrsModes() as well as by PrsMgr_PresentationManager.

It looks unreasonable having 2 duplicated mechanisms for invalidating presentations, so that one (first) should be removed and replaced by another.
