Destructible lines don't take explosive damage

[dodopod]

If there is a step between an explosion and a destructible line, the line won't take damage. I haven't looked at the code, but I'm guessing that damage is based on a LOS check between the pos of the explosion, and the bottom of the line's mid-texture. I've noticed weird things happen when damaging floors, too (in the demo for my destructible geometry handler, firing at the grass with a rocket launcher only damages the 4 adjacent squares) so there may be a similar issue with that.

Is this related to Hexen's stained glass windows too? Don't know how they're setup, but they're also unaffected by splash damage. Strife's computer terminals and screens too iirc.

That are plain shootable walls, they require impact damage.
