This change add a breaking change in the
viewer.getSnapshot()API. I use theviewerwith a distance measurement plugin with a specified container that is notdocument.body. But since this change, when a get a snapshot of the viewer, a canvas is also added on thedocument.body. I propose to add acaptureparameter ongetShapshotto prevent this behaviour if not requested (must be set totrueif capturedcanvasare desired).
