Fix T42106: Box image mapping shows black triangles if they point to a corner and blend is 0 

After discussion with cambo here we decided it's better to choose arbitrary side of the box
(in this case it's X-axis) and use image from it. That's better than doing a blackness.

P.S. This is literally a corner case anyway.
