Built with NetBeans 8.0 Patch 2 for Mac, build 201403101706.

Issue: The graphics in the main routing screen do not display. Instead of seeing the board, the program draws only the gray background. Many of the UI buttons do not paint either but do still respond to mouse clicks. Otherwise the program seems to function normally.

Detail: In several drawing routines found in boardgraphics/GraphicsContext.java, the original author attempts to cast a Shape into a Rectangle which leads to an exception on my system. An example from line 130 of GraphicsContext.java:
Rectangle clip_shape = (Rectangle)p_g.getClip() ;

I was able to avoid an exception by changing the line to read:
Rectangle clip_shape = p_g.getClip().getBounds()

The same fix needs to be applied to lines 130, 273, 313, and 432. On my machine, fixing these lines brought the graphics back, everything looks normal.
