Description
Piccolos piccolox.PFixedWidthStroke is buggy and generates missing initial moveto in path definition errors with a IllegalPathStateException? that cannot be caught because it is in the automatic repaint function.
Stacktrace: Exception in thread "AWT-EventQueue?-0" java.awt.geom.IllegalPathStateException?: missing initial moveto in path definition
at java.awt.geom.Path2D$Float.needRoom(Path2D.java:263) at java.awt.geom.Path2D.closePath(Path2D.java:1752) at edu.umd.cs.piccolox.util.PFixedWidthStroke$FillAdapter?.endPath(Unknown Source) at sun.dc.pr.PathStroker?.endPath(Native Method) at edu.umd.cs.piccolox.util.PFixedWidthStroke.createStrokedShape(Unknown Source) at edu.umd.cs.piccolo.nodes.PPath.getPathBoundsWithStroke(Unknown Source) ...
Reproducibility: It is not reproducible very well. Best test case is: Loading a logical model (toymodel), export layout, select mode 'Editing', move nodes around, import layout. Sometimes the exception is thrown.
This bug in known by the piccolo team (see issue tracker of piccolo) and other people, e.g. http://www.sfr-fresh.com/unix/privat/tesseract-2.03.tar.gz:a/tesseract-2.03/java/SVWindow.java. In the next piccolo version the bug might be fixed (it is on the agenda).

This issue needs more testing. Maybe it can be avoided in some cases. This bug is also discussed in #117.
