JGraphpad

This release fixes issues with artifacts being
left on the screen while dragging. A memory leak
was fixed and a few performance improvements were
made. Various Javadocs were tidied up and warnings
were removed. The performance for drawing of
Bezier edges has been improved. Also, a licensing
exception has been added. The main license remains
the GPL, but if JGraphpad CE is used within
Netbeans RCP with other LGPL code, it may now be
used under the terms of the LGPL also. This makes
it legally possible to use with Netbeans RCP,
while all other uses are still covered by the GPL.

There was an issue with the binary distribution of
JGraphpad Community Edition 5.7.3.1.1 which
prevented it from running on a 1.4.x Java Virtual
Machine. This has been corrected in this release.

This release compiles with JGraph 5.7.3.1. Toolbox buttons to create edges or vertices no longer persist selection state. The former behaviour can be restored by setting GPMarqueeHandler.remanent to true. The GPMarqueeHandler, GPGraph, DefaultGraphModelFileFormatXML, and GPUserObject classes were moved to org.jgraph and their constructors are now protected so that JGraphpad is easier to extend from as a library without changing its code. Various warnings were removed and a general code cleanup undertaken.

This release is an update to compile with the 5.7 release of JGraph, fixing changes to the API with the routing functionality changing slightly.

The release now compiles with JGraph 5.6.3,
changing the use of graph references in various
renderers. Some unused code was removed and
various Javadocs were cleaned up.
