question about car models & double sided faces

[alex25]

i still think it would be nice to enable double-sided textures only for selected objects

Yes, that's a good point, double sided-ness makes more sense as a per-object flag instead of a per-track flag. I'll add it to the issues list....

it turns out it's trivial to implement double sided-ness on a per texture. basically i just extended the blend flag to mean one for transparent blended texture and 2 for double sided texture.

this is the patch:

if there are no objections i can commit it to svn and start updating the tracks to take advantage of this feature.
