orthographic projection and visualMap selection causes a zoom reset

[helgasoft]

Preconditions:   grid3D.viewControl.projection:'orthographic' and visualMap.type:'piecewise'
User action:     first zoom in/out, then select/deselect from visualMap
Result:       chart's zoom is reset
Note:       it works fine with projection: 'perspective'

User action: first zoom in/out, then call setOption method to set new data.
Result: chart's zoom is reset
Note: it works fine with projection: 'perspective'
