Undo feature functions differently based on MarkerType: FreehandMarker

[jljohnson001]

Steps to reproduce:

• Select FreehandMarker icon
• Draw multiple shapes
• Select Undo

Expected behavior:

• Most recently drawn item is removed (other MarkerTypes appear to function this way)

Actual behavior:

• All items drawn using FreehandMarker are removed

Note: If this is expected behavior, I will modify my request to include this detail in Marker2JS docs.

FreehandMarker

Undo

FreehandMarker is a very special type of marker in marker.js as the drawing is done in another context. So it only hits the "undo" subsytem after the drawing is done. The way to mitigate this is the newFreehandMarkerOnPointerUp setting. This way undo will work as you expect, but each drawn part (mouse down to mouse up) will be a separate marker.

Good point about documenting this somewhere! Thank you.
