       png, svgz, svg, xpm exact match
       png, svgz, svg, xpm best match
       less specific fallback in this theme: png, svgz, svg, xpm exact match
                                             png, svgz, svg, xpm best match
       even less specific fallback in this theme: [same order]
       (...)

       next theme in inheritance tree: png, svgz, svg, xpm exact match
                                       png, svgz, svg, xpm best match
       less specific fallbacks in this next theme

       less specific fallbacks in this next theme
       (...)

       and so on.

       If size parameter is a non-standard one, then we give more preference to
       SVG format since drawing SVG's gives better quality and despite being
       slower than resizing a PNG image, the cases where non-standard sizes are
       asked are very rare. For non-standard sizes what we have is:

       svgz, svg, png, xpm exact match
       svgz, svg, png, xpm best match
       less specific fallback in this theme: svgz, svg, png, xpm exact match
