JOGL/AWT: Fix ~ 2 year old regressions: Choose & Use GraphicsConfiguration for Canvas. ; Adding FSAA test.

Canvas/X11:
  The Canvas GraphicsConfiguraton should be chosen before the native peer is being created.

Choosing AWT GraphicsConfiguration (all platforms):
  Don't filter our capabilities with 'AWTGraphicsConfiguration.setupCapabilitiesRGBABits(capsChosen, gc)',
  not necessary (see above) and it would remove ourrequired alpha channel.

Canvas display():
  Don't render if drawable is not realized (yet).
