rle_putrow - Write a row (scanline) of data to an RLE file.
#include <rle.h>
void rle_putrow( rows, length, the_hdr );
rle_pixel ** rows;
int length;
rle_hdr * the_hdr;
Rle_putrow is called for each output scanline when creating an
RLE(5) image. Rows is an array of pointers to the pixel data for
the color components of the scanline. Rows should have
the_hdr→ncolors elements. If an alpha channel is being
saved, rows[-1] should point to the alpha channel data. Length is the
number of pixels in the scanline. Rows[i] should point to the
the_hdr→xmin element of the scanline.
The function rle_row_alloc(3) will properly allocate memory
for use by rle_putrow.
rle_hdr(3), rle_skiprow(3), rle_putraw(3),
rle_puteof(3), rle_row_alloc(3), rle_row_free(3),
librle(3), RLE(5).

Having the scanline indexed from xmin is an incredible botch. Its origin
lies in the deep dark history of the raster toolkit, and it seems it's too
late to change it now.
