[josm-dev] icons for MapCSS for RoadSigns

I thought adding a layer and a z-level would help:

/* Now render the traffic sign */
    z-index: 10;
    icon-image: eval(concat("data:image/svg+xml,<svg width='100px'
    icon-width: eval(max(12,prop(pixel_per_metre)));

It looks really funny, as the set of signs scales and the default style

But unfortunately it's not different from not adding those directives.
