It's because we need to do the equivalent of :

        xpm_col.name = NULL;
        xpm_col.value = "none";
        xpm_col.pixel = backgroundcolor;
        xpm_attr.valuemask = XpmColorSymbols;
        xpm_attr.numsymbols = 1;
        xpm_attr.colorsymbols = &xpm_col;
        XpmCreatePixmapFromData(display, RootWindow(display,screen), nofill_xpm, 
&nofill, &dummy, &xpm_attr);

to replace the none pixel with our background colour. Xpm is pretty stupid.
