static void _draw_end_marker ( cairo_t *  cr, const grad_point_t  endpoint, const grad_point_t  opposite, const float  zoom_scale, const float  normal_sign, const gboolean  active  )

static

Draw one triangular endpoint marker on the graduated line.

The marker geometry is built from the active endpoint and the opposite endpoint, then mirrored with normal_sign so the two markers keep opposite winding while sharing the same drawing path.
