Using the 10/19/13 release of jogl: on OSX, using setBounds on GLCanvas only seems to set the origin initially.  Subsequent setBounds calls only set the height/width and leave the lower left location of the window the same.

I modified my test to animate moving the canvas across the screen while changing its size.  The window should move to the right, getting shorter and wider as it goes.  It works for the latest jre in windows (7u45) but fails under the 1.7.0_45-b18 in Safari on OSX 10.8.5.  It does work correctly if you run it on the command line in OSX though.
