Click and drag on the gray area, the point cloud should stretch.

As you can see it's quite fast but the dots are in a terrible sqashed mess. It'd be natural for these to not deforme with the "ground", which is what `vector-effect="non-rotation"` is supposed to accomplish.

But because this is not implemented, we need to emulate this behavior with js, by clicking this button.

As you can see, this is terribly slow.

Having this feature would allow great plotting tools to work directly with SVG. As you can see, existing tools either rely on non-continuous navigation (jumping static views), or canvas/webgl. This is a pity since SVG already implements user interaction (clickable things etc...), and is also exportable to be imported into many documents.

I hope this demo is convincing enough to tell how useful all variants of vector-effect could make web based plotter.
