Description

In my application (OpenPnP, http://openpnp.org) I use Batik to render SVG icons for the user interface. Recently it's been noticed that some of the shapes in the icons become distorted. In comparing the same file rendered by several other SVG renderers it's clear that Batik is rendering small circles (and maybe other shapes) incorrectly. The issue can be seen in the attached image quite clearly.

The source SVG is also attached. The file was created in InkScape, but I have also tried exporting it from AutoDesk Graphic and get a similar result. The icon is rendered at 24x24.

I have also attached the Java code I use to render the icons in SvgIcon.java.
