Extension for material properties?

[Lasse Deleuran]

I like this idea.

We could reuse one of the 'useless' color ranges (like the invisible ones).

I like this since it allows legacy software to be able to use a new ldconfig.ldr and default to still show colors correctly.

You and me might like this because it is neat because we see masks with the possibility of describing surfaces. However. I fear that we might make it too difficult for less technically inclined users.

For this reason I also want us to consider META statements, such as something like this impacting the next line:

0 !SURFACE [ROUGHNESS=0.8] [OTHER_FEATURE=VALUE] ...
1 2 0 0 0 1 0 0 0 1 0 0 0 1 subfile.dat
