#113 Can't extend PluggableRenderContext

[kgurie]

AREA/CLASS/EXAMPLE AFFECTED:
JUNG2
edu.uci.ics.jung.visualization.PluggableRenderContext

It doesn't look like PluggableRenderContext can be subclassed outside its package. The only constructor has default package-private visibility.

SAMPLE FIX/WORKAROUND: Change the visibility to 'protected'
