in repository l3svn.

commit 290e62b8bf38faa86f1116bc33cf07c5092baccd
Author: Joseph Wright <joseph.wright at morningstar2.co.uk>
Date:   Tue May 10 08:18:17 2016 +0100

    Add basic dvisvgm support
    
    At present this covers color/rotation/scaling but not clipping:
    the latter is trickier.
