Hello, first of all thanks for adding the Winkel Tripel projection. I want to create a SVG with Winkel Tripel but got some problems: there seems to be rounding errors somewhere because the country polygons I export don't fit together anymore in the SVG. But the same rendering as PNG looks good.
There are also some error messages while rendering. (see below) The PRJ I use for Winkel Tripel is: PROJCS["World_Winkel_Tripel",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Winkel_Tripel"],PARAMETER["Standard_Parallel_1",50.467],UNIT["Meter",0.1]] The data is in WGS84 (shapefiles). Any idea what could be the reason why it works as PNG but don't as SVG?
