[MS4W-Users] Cairo

[Emmanuel Belo]

Hi Jeff,

Camptocamp is very interested in having svg support in Mapserver, also for
linux versions. As I understand, this implies moving to librsvg or
developing a compatibility layer. See
http://lists.osgeo.org/pipermail/mapserver-dev/2012-January/011901.html

How could we setup a xfounding effort on this?

Best regards,

Emmanuel Belo
