// This workaround code was taken from PCL library(www.pointclouds.org)
//
// Modified by Jasper Shemilt to work with VTK 6.2
// The fix was needed because GetCocoaServer has been moved from
// vtkCocoaRenderWindowInteractor to vtkCocoaRenderWindow in VTK 6.2.
// This alteration to VTK happened almost a year ago according to the gitHub
// commit a3e9fc9.
