Changes for 2.0.14

• Added DraggingOptions.groupsAlwaysMove, which determines whether Groups move their member parts even if those members have. Part.movable and Part.copyable set to false.
• Improved the way Graduated panels decide whether or not to draw ticks based on Diagram.scale. It is now based on the approximate pixel distance between ticks. If they would be rendered too close together, they will be skipped.
• Fixed an infinite loop bug with ContextMenuTool when invoked by CommandHandler.showContextMenu on a GraphObject.click event.
• Minor fixes for using GoJS within Puppeteer, for making SVG.
