ParallaxTest

ParallaxTest is an unfinished shader since (although not available in SDK 2013) which draws parallax mapping on an albedo. Alternative to the disabled $parallaxmap shader parameter. Accepts only a $basetexture, of which the alpha channel is used as the heightmap.

Bug:The material will always be drawn unlit.  [todo tested in ?]

Todo: Document/test more of this shader!
