Deletes a triangle from a mesh starting at TriIndex, leaves any verts that were attached untouched. DoSwap should be much, much faster for large meshes, but will reorder the final triangle to fill the gap in the array. All other indexes will be the same still. Without swapping, the entire array after the deleted triangle has to be shifted down 3 times.
