Changes for 2.0.13

• When dragging over a different Diagram than the source, such as in a drag from a Palette, the DraggingTool now checks the Diagram's cursor and only changes it to  "copy"  if the Diagram.currentCursor value is  ""  or  "auto" .
• Drawing fix for some objects disappearing when rotated, and the Diagram is scaled.
• Optimized Group.move not to try moving member parts when the offset is zero. This improves the stability of layouts that move groups, such as PoolLayout in some samples.
• This bugfix potentially breaks old  elementFinished  code in Shape geometries with multiple figures.  Fix for Diagram.makeSVG  elementFinished  optional argument: Shapes with multiple geometry figures would pass the final SVG  <path>  generated as the SVG element, when they should be grouped together and pass an SVG  <g>  instead. This is what TextBlock already does when there is more than one line of text.
