NAME
	WritePixelLine8 -- write the pen number value of a horizontal line
	of pixels starting at a specified x,y location and continuing
	right for count pixels. (V36)

   SYNOPSIS
	count = WritePixelLine8(rp,xstart,ystart,width,array,temprp)
	D0                      A0 D0:16  D1:16  D2    A2    A1

	LONG WritePixelLine8(struct RastPort *, UWORD, UWORD,
	     UWORD, UBYTE *, struct RastPort *);

   FUNCTION
	For each pixel in a horizontal region, decode the pen number selector
	from a linear array of pen numbers into the bit-planes used to describe
	a particular rastport.

   INPUTS
	rp    -  pointer to a RastPort structure
	(x,y) - a point in the RastPort
	width - count of horizontal pixels to write
	array - pointer to an array of UBYTEs from which to fetch the pixel data
	        allocate at least (((width+15)>>4)<<4) bytes.
	temprp - temporary rastport (copy of rp with Layer set == NULL,
	         temporary memory allocated for
	         temprp->BitMap with Rows set == 1,
	         temprp->BitMap BytesPerRow == (((width+15)>>4)<<1),
	         and temporary memory allocated for
	         temprp->BitMap->Planes[])

   RESULT
	Count will be set to the number of pixels plotted

   NOTE
	width must be non negative
