Qu'est-ce que c'est "quality of the build"?

Ah poo.

That Apocolypse pigment was a tiny background object and I wasn't 
*really* concerned [1], but I just noticed one of my foreground objects
	texture {
		pigment {Jade}
		finish {
			ambient 0.3
			reflection 0.05
			diffuse 0.7
			roughness 0.3
		}
		scale 5*inches
	}
looks completely different.  It smells like the povdos version is 
ignoring the scale 5*inches.  I definitely have to RCA this.

[1] you can't even really tell in the video. But I use an ancient ACDSee 
to flip lossless png files at 18 fps during development, and there it 
was noticable.
