[Bf-committers] mat_nr confusion

[Alexander Ewering]

Hi,

I'm currently trying to make material indices for text objects work
reliably and consistently once and for all, and I'm still having
issues understanding material indices at code level.

  - What is ob->actcol *exactly*?

  - What is ob->totcol *exactly*?

  - What are things like nu->mat_nr? It seems they're the material
    index _-1_ ? How does this work if no material indices exist?
    Is it -1 then?

  - What is this ob->colbits business?

Sorry, hard to think clearly these days.

Ton, before I look for ages in the code with countless debug printfs,
maybe you could give me a few quick answers.

Thanks.
