Improve performance of re-parenting hggroups. * graphics.cc (hggroup::update_axis_limits (string, graphics_handle): Resize "limits" to 1x4 vector, not 4x1. Get handle to hggroup and call update_axis_limits with this handle so that the update starts higher up the tree with hggroup rather than the child of the hggroup. * graphics.cc (hggroup::update_axis_limits (string): Resize "limits" to 1x4 vector, not 4x1.
