Wood pigments:
Several wooden pigments by Tom Price:
	
		- Cherry_Wood

- Tom_Wood

 		- DMFWood1, DMFWood2, DMFWood3, DMFWood4, DMFWood5
- The scaling in these definitions is relative to a unit-sized object (radius 1). 
			Note: woods are functionally equivilent to a log lying along the z axis.  For 
			best results, think like a woodcutter trying to extract the nicest board out of that 
			log.  A little tilt along the x axis will give elliptical rings of grain like you'd 
			expect to find on most boards. Experiment. 
Wood textures:
	- DMFWood6
- This is a three-layer wood texture.  Renders rather slowly because of the transparent 
		layers and the two layers of turbulence, but it looks great.  Try other colors of "varnish" 
		for simple variations.
- DMFLightOak
- Is this really oak?  I dunno.  Quite light, maybe more like spruce.
- DMFDarkOak
- Looks like old desk oak if used correctly.
