  [BUG?] woods.inc - T_Wood12

Hi,

I think I found a little bug in the wood.inc include file. When I render 
the texture T_Wood12 I get strange patterns. Have a look at the 
attachment please. The problem is caused by the two textures that are 
overlayed in the definition of T_Wood12 in woods.inc. Rotating one 
texture by 90 degrees on the y-axis solves this. So I searched deeper in 
wood.inc and found the definition of the wood grain:

#declare P_WoodGrain12A =
pigment {
     bozo
     turbulence 0.04
     lambda 2.5
     omega 0.1
     octaves 7
     scale <0.5, 0.05, 0.05>
}

The scaling of 0.5 for the x-value should be 0.05 and the scaling for 
the z-value should be 0.5. Then everything looks o.k. without rotating 
one texture.

I hope this makes any sence. :-)

So long,

Bonsai
