Allow Insight 3D process maps to be exported as a generic 3D image format

[#1]

Currently, it is possible to export Insight workspaces as .png files - i.e. as a 2D image file that can then be manipulated in photoshop.

It would be great if we had the capability to export 3D process maps as a 3D image file. This would enable, for example, the potential to animate the image in 3D, thus making it much more engaging when presenting the infographic back to the business users.
