3D preview of a 'convert to height' conversion does not show what is expected

[GoogleCodeExporter]

See attached screenshot.

The 3D Preview for a 'Convert to height' operation does not show anything 
useful, since all 'bump mapping' options still assume that the input texture is 
a normal map.

Ideally, I would like to see a bump/parallax effect preview making use of the 
output height texture.
