No, but It won't compile without it either. At least not here. My IDE tells me to make it static, but i don't understand why.

   But the problem was that you were using 'java.awt.Color.RED'
not 'java.awt.Color.red'.  What is below works.

Someone should do a thorough howto on using an overlay in a jsvgcanvas and put it in the wiki. At least I think so :)

   Using an overlay is pretty trivial, your problems seem to mostly be
with the Java language.  This is not an appropriate forum to learn
Java.  There are _lots_ of resources for that.
