triangles. It is possible to end up with such nodes using brushes in aggressive collapse mode. Those nodes should normally be cleaned up, since they can never be actually reused (adding more geometry to a node requires the node having some geometry to begin with) but until we support dynamic nodes, better delete those to avoid binding graphics driver resources. If such zero elements buffers were used, GL error out of memory would be reported.
