True if the data has changed since the last RenderBase.update.

True if one of the properties has changed since the last RenderBase.update.
True if the size of the visualization has changed since the last RenderBase.update.
Represents the reason why rendering should take place. An object of this class is passed in UpdateInfo in a call to RenderBase.update. The renderer can use the information in this class to optimize rendering. For instance, if only the decorations have changed, the renderer could decide to execute code that only updates the highlight and selection state (rather than rendering the entire visualization).
