Possibly related to #585, we (MapOSMatic) are seeing a strange issue on our upcoming version of our map rendering engine when outputting to PNG.

When telling Mapnik to render to a Cairo surface that is scaled with cairo.Context.scale(), the font size of text labels that have a halo_radius is inconsistent. The attached screenshot should be self-explanatory.
