partially rollback b93c760b33 - meaning that radii will continue (as in Mapnik 2.0.0) to be assumed for marker width/height in the Mapnik 2.0.x series (>= 2.0.2) - closes #1163, refs #1134

 Mapnik 2.0.2
 ------------
 
+- Rolled back change made in 2.0.1 to marker width/height meaning that Mapnik > 2.0.2 will stick to assuming width/heigh are radii for back compatibility with 2.0.0. The reverted change is seen below as "Fix Markers rendering so that ellipse height/width units are pixels (previously were unintentionally radii)". Issue tracking this is #1163
+
 - XML: Fixed to avoid throwing if a `<Parameters>` element is encountered (which is supported in >= 2.1.x)
 
 - Support for PostGIS 2.0 in the pgsql2sqlite command (e69c44e/47e5b3c)
