UPDATE: There is much better way of doing this, by using Windows Enhanced Metafile instead of Scalable Vector Graphics.
When making my custom Nutanix stencil package I ran into problems with shape sizes. Larger shape sizes increase the time to pull the shape from stencil to drawing. The more complex shape (with multiple sub-shapes) you have the larger it will be. Some of my original Nutanix shapes became so large that it took few minutes to pull shape into a drawing.
