p_maputl.c	PIT_AddLineIntercepts	Takes a linedef and adds it to the trace intercepts list. Does nothing if the line is wholly to the side of or behind the trace.
p_maputl.c	PIT_AddThingIntercepts
p_maputl.c	P_AproxDistance
p_maputl.c	P_BlockLinesIterator
p_maputl.c	P_BlockThingsIterator
p_maputl.c	P_BoxOnLineSide
p_maputl.c	P_InterceptVector	Returns fixed point percentage of finite vector 1's length until intersection with infinite vector 2. Negative values indicate intersection behind vector 1's starting point, while above 1.0 means past vector 1's ending point.
p_maputl.c	P_LineOpening
p_maputl.c	P_MakeDivline
p_maputl.c	P_PathTraverse	Calls the given callback on each thing/linedef hit in the path between two points, in order from the shortest to farthest distance to the first point. Ignores lines wholly to the sides of or behind the trace (via PIT_AddLineIntercepts), and those behind the trace (via P_TraverseIntercepts).
p_maputl.c	P_PointOnDivlineSide	Same as P_PointOnLineSide, except the cross product calculation suffers even precision loss for the line and point. An additional optimisation is in place, which adds one irregular bias for a point exactly on the line: if the line is tilted facing northeast and the point is on the first (southeast) vertex, the point is considered in front.
p_maputl.c	P_PointOnLineSide	Returns 0 when the point is in front of the linedef, 1 when it is behind the linedef. The implementation uses the cross product formula to determine sidedness if faster checks are inconclusive. This calculation is done in a way that suffers precision loss mainly for the line. The alternative function P_PointOnDivlineSide offers evenly spread precision loss. Bias exists to account for points exactly on lines. This bias can be summarised as BURN: Back Unless Right Negative (point on line is on the backside unless the line is right-angled and facing a negative direction (south or west)).
p_maputl.c	P_SetThingPosition
p_maputl.c	P_TraverseIntercepts	Runs the given callback for intercepts in nearest to farthest order. Only called by P_PathTraverse, which specifies that this function disards all intercepts farther than the trace line's end.
