annotate artifacts/src/main/java/org/dive4elements/river/jfree/EnhancedLineAndShapeRenderer.java @ 7119:988dde49ae65
Fix area label rendering.
Previously the showarealabel setting was neither parsed nor
used to decide if the arealabel should be drawn.
It is mostly off but enabled for Cross Sections. It is now
also shown in the style editors in case someone got used to it ;)
