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->BytesPerRow == (((width+15)>>4)<<1),
             and temporary memory allocated for
             temprp->BitMap->Planes[])

RESULT
    For each pixel in the array:
        Pen - (0..255) number at that position is returned

NOTE
    width must be non negative
