Tiles can now be exported, with either the UDIM or UVTILE numbering scheme. Exporters for PNG, SVG and EPS were updated. The vector formats simply offset the view, so all UVs can end up being exported multiple times. Only tiles containing UV points will be exported. In theory, this may result in some polygons being ignored, if they cross a whole otherwise empty tile, but this should not happen in practice.
