This header file contains prototypes for the functions used to draw individual wall segments (or "segs").

Function name	Return type	Params	Defined in	Description
`R_RenderMaskedSegRange`	void	`drawseg_t` `*ds`, INT32 `x1`, INT32 `x2`	`r_segs.c`	Renders a masked seg (a segment of a middle texture for a double-sided linedef) in the given range.
`R_RenderThickSideRange`	void	`drawseg_t` `ds`, INT32 `x1`, INT32 `x2`, `ffloor_t` `pffloor`¹	`r_segs.c`	Renders a thick side (a segment of an FOF wall texture) in the given range.
`R_StoreWallRange`	void	INT32 `start`, INT32 `stop`	`r_segs.c`	A wall segment will be drawn between start and stop pixels (inclusive). This function also handles clipping for adjacent floor/ceiling planes, marking the boundaries of where their floor/ceiling textures can be drawn later in the same tic. The following can be drawn by this function via `R_RenderSegLoop`: bottom and/or top textures if they exist, if the wall segment's linedef is double-sided the middle texture only, if the wall segment's linedef is one-sided (i.e.: has no back sector). The following won't be drawn by this function, but may be detected and marked to draw later in the same tic: middle textures for double-sided linedefs any unblocked segments of FOF wall textures present between the highest and lowest points of the wall segment

¹ Named "pfloor" instead in the function definition given in r_segs.c
