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.

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.
