Preliminary fix for

Issue 216: Cannot create GLCanvas on non-default GraphicsDevice

Made JOGL Xinerama-aware; now uses screen 0 rather than the screen
reported from the AWT GraphicsDevice when Xinerama is enabled. So far
only compiled and tested on non-Xinerama configuration on Linux; more
testing needed on Xinerama setups and on Solaris.
