Externs

Data name	Data type	Non-extern location(s)	Description
*firstseg	drawseg_t	r_bsp.c	Temporary pointer to the first drawseg created in the current subsector being rendered through R_RenderBSPNode. This is non-NULL only if the subsector has any "fake floor" (FOF or PolyObject) planes, so it can store: the number of fake floor planes to be drawn (->numffloorplanes) an array of pointers to the fake floor planes themselves (->ffloorplanes) an array of front scales for each column (->frontscale) firstseg will be set to NULL again for the next subsector rendered.
