I'm pretty sure this is not a problem for GTS. The GTS algorithm (gts_bb_tree_overlap()) is an axis-aligned bounding-box tree algorithm. It only operates on bounding boxes of cells, so the orientation is irrelevant. This is also why the algorithm can be used for tetrahedral meshes, even though GTS supposedly is only for triangulated surfaces.
