WebGL renderer

I've yet to understand completely how color works, but i got that 16 is actually the "current color",
and i correcly substitute >it with what "parent lines" says, it's not hardcoded to 0. What i miss is the whole "complementary" colors and code 24.

As Philo already answered, colors 16 and 24 are for "use parent color".
I just asked to correct the implementation of "what to do when there's no parent".
For example, I put some unofficial part from the parts tracker into your tool.
Then it gets all black, because you map color 16 to "parent color", and when there is no parent,
then use 0/0/0. My only, very simple, request was, as color 16 for this purpose has a R/G/B value
set in ldconfig.ldr, that you use _that_ color from there when there's no parent, instead of 0/0/0

Normal edges would be trivial, conditional edges will be not

I know, I was asking just for the simple, normal edges.
