offsets: Line_AlignCeiling and -Floor

[simc]

(With zdoom-2.9pre-928-g841a579)
The alignment offsets of the ceilings and floors with the conventional Hexen/Doom format doesn't work as it did earlier.

The map has a line with type: 121: Line_SetIdentification (lineid, ...)
The script has: Line_AlignCeiling (lineid, ...);, Line_AlignFloor (lineid, ...);

The flats are alinged to the correct directions but their offsets seem totally random. Here's a test wad for Doom2, MAP01.

fixed the initialization part, so it's correct in GZDoom again.
Unfortunately the texture mapping in the software renderer is quite broken at the moment and this is also affected by it.

Just wondering: Is this still an issue in QZDoom?

Yes, it is. The offsets are still off.

Fixed.
