Wood pigments:

Several wooden pigments by Tom Price:

`Dark_Wood`

  A very pale wood with tan rings -- kind of balsa-ish.

`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.
`EMBWood1`
