How can I get the current zoom factor for a map?

Is there a way get retrieve the zoom factor for a map?  

i.e. where you set it via:  mte.zoom(scale, time, transition)

The zoom factor is just the scale of MTE’s masterGroup.

local mapObj = mte.getMapObj() print(mapObj.xScale, mapObj.yScale)

The zoom factor is just the scale of MTE’s masterGroup.

local mapObj = mte.getMapObj() print(mapObj.xScale, mapObj.yScale)
