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);
}
