In GZDoom 4.6.0, the planeanchor argument on Line_SetPortal no longer works. It just bricks the portal when set to 1 or 2, instead letting you see the void (or sometimes other sectors/functional portals/janky stuff from your map).

Plane anchoring was working fine in GZDoom 4.5.0: for visual portals (type 0 or 1) you could line up floors or ceilings, which allowed you to have multiple portals (at different sector heights) that view the same portal exit.
