it would be great to have a much faster version of resample(1),
possibly as a library function...

then it would be easy to do what you want in rio.

Replicating the image is only one alternative. I have quite beautiful
results with streching an image. On a 1600x1200 monitor the antialiased
image: (with k=black b=blue g=green r=red p=purple)
kkgk
bkkp
krkk
produces striking results. this works under windoze & several wms under
linux. And with plan9 I get a plain grey background. *sigh*

actually, it should be trivial to make it cope with either of the
above.

a) use readimage(2) to read in the image (this copes with compressed images)
b) call replclipr to make the image replicated; that way an image smaller
than the screen will tile correctly.

something like: (untested)

void
iconinit(char *bgimage)
{
	int fd;
	if (bgimage != nil && (fd = open(bgimage, OREAD)) != -1) {
		background = readimage(display, fd, 1);
		if (background != nil)
			replclipr(background, 1, display->image->r);
		close(fd);
	}
	if (background == nil)
		background = allocimage(display, Rect(0,0,1,1), RGB24, 1, 0x777777FF);
	red = allocimage(display, Rect(0,0,1,1), RGB24, 1, 0xDD0000FF);
}

the idea may be heretical, but i've added a '-w' option to rio that
draws an image from an uncompressed image(6) file on the "root
window".  it expects an image the same dimensions as the screen and
(can't|won't) cope with repainting the background when rio is running
in a window smaller than the image, but that's okay.

the beauty is that even a halfwit like me could figure it out in less
than an hour.  :)

my background images are various black & white photos from the library
of congress "american memory" collection, mostly of steam trains.
