[PATCH] d2d: Suppress last empty segment also for D2D1_FIGURE_END_OPEN

[Stefan Brüns]

When the last vertex is coincident with the first vertex, the last
segment should be suppressed for both END_OPEN and END_CLOSED.

When the last, zero length segment is not omitted
d2d_geometry_intersect_self will add invalid segments.
