You're developing a killer module for the Object Collection, and you
discover an oversight in one of your macros.  You repair the oversight,
but it needs testing, so you write a test scene.  The colors are not right.

You rack your brain over the macro.  You stare at #debug output and GIMP
samples.  You convert back and forth between linear and sRGB.  You
compare the macro with a successful proof-of-concept you wrote two
months earlier.  You start to wonder if you have some grave
misunderstanding of how POV-Ray works.  You divide by the finish diffuse
to see if that's interfering, but the numbers still don't match up.  You
run a case using just gray scales, and discover that the diffuse value
/couldn't/ be the problem.  Everything checks out in the SDL, but the
image is still wrong!

After several hours of this, you discover that the bug is in test scene

Oy, vey.
