[Tilesathome] Strange svg code for areas

[Jiri Klement]

Hi,

Is there a reason why code generated for areas looks like this?

<path id="area_24063746" d="..."/>
<use xlink:href="#area_24063746" class="amenity-school"/>

The <use> seems to be redundant, following code is doing the same thing:

<path id="area_24063746" d="..." class="amenity-school"/>

Generate pngs seems to be exactly the same, though they are not the
same in byte by byte comparsion.
