Merge branch 'horizon_lines' into 'master'
Horizon lines Horizon lines for software mode! Place a Linedef type 41 somewhere on a one-sided linedef and it'll do fancy rendering hacks to draw the adjacent floor/ceiling to the "horizon". One small thing to sort out when I remember to do so, but this is good enough for merge already. See merge request !44
