Changes for 2.0.5

• Fix for Shape.defineFigureGenerator where it would incorrectly throw an error on Geometry bounds being too large, when they were not.
• Some touch events would cause [intervention] warnings in some browsers when canceled because GoJS would call preventDefault on non-cancelable events. This has been fixed.
• Fixed a bug with Diagram.zoomToFit when Diagram.scrollMode was set to Diagram.InfiniteScroll.
• Fixed a bug where GuidedDraggingTool was snapping the whole part to a guideline instead of the location object.
