Well there is the well-known CSG stencil trick, as mentioned in the red
book, and also employed in OSG's stencil shadow algorithm, but this
seems like overkill for such a simple problem as taking the vertices
from an inner tube wall and stitching them into a triangle strip with
the vertices from an outer tube wall...
