toRawSvg does not display individual strokes if controller is initialized with points

[rfitz123]

If I take the points from one controller and initialize another with those points, toImage will work as expected, but toRawSvg will connect individual strokes together, exactly like #87.

This is due to the fact that toRawSvg is using _latestActions to determine strokes, as opposed to the PointType of each point, which is how strokes are distinguished everywhere else.

I would venture a guess that toRawSvg should split points into strokes based on PointType (same as the other methods of drawing) rather than piggybacking on _latestActions, which is only used to support undo/redo functionality. If I'm initializing a controller with points, I would not necessarily expect undo/redo functionality to be supported, but I would definitely expect toRawSvg to distinguish between separate strokes.

Workaround

We are storing signatures as strokes on our side, so our workaround was to loop through the strokes, setting points and calling pushCurrentStateToUndoStack for each stroke. This will populate _latestActions with a list of strokes as toRawSvg expects.
