// another line, it appears that the line angle is inherited from the
// father line. Due to roundoff, the new vertex may have been placed 'off
// the line'. When you get close to such a line, and it is very short,
// it's possible that the roundoff error causes 'firelines', the thin
// lines that can draw from screen top to screen bottom occasionally. This
// is due to all the angle calculations that are done based on the line
// angle, the angles from the viewer to the vertices, and the viewer's
// angle in the world. In the case of firelines, the rounded-off position
// of one of the vertices determines one of these angles, and introduces
// an error in the scaling factor for mapping textures and determining
// where on the screen the ceiling and floor spans should be shown. For a
// fireline, the engine thinks the ceiling bottom and floor top are at the
// midpoint of the screen. So you get ceilings drawn all the way down to the
// screen midpoint, and floors drawn all the way up. Thus 'firelines'. The
// name comes from the original sighting, which involved a fire texture.
//
// To correct this, reset the vertex that was added so that it sits ON the
// split line.
//
// To know which of the two vertices was added, its number is greater than
// that of the last of the author-created vertices. If both vertices of the
// line were added by splitting, pick the higher-numbered one. Once you've
// changed a vertex, don't change it again if it shows up in another seg.
//
// To determine if there's an error in the first place, find the
// angle of the line between the two seg vertices. If it's one degree or more
// off, then move one vertex. This may seem insignificant, but one degree
// errors _can_ cause firelines.
