Texture warping on cuboid fuel tanks.

Textures dont update for fuel tanks that have edges/arent perfectly cylindrical; causes texture warping – particularly noticable with the "rivets" texture.

Not a technically a bug, but should be fixed nonetheless.

maybe textures should only update if the tank has somewhere from 5% to 0% corner curvature, that way only one new (rectangular) texture would have to be made (per current texture).
