Bug 1210 - Use manual impl. XRenderFindVisualFormat instead of buggy generated version

- XRenderDirectFormat XVisual2XRenderMask(..):
  - Move from JOGL's X11GLXGraphicsConfiguration -> Nativewindow X11GraphicsConfiguration
  - Always use manual impl. of XRenderFindVisualFormat

Additionally:

- Add X11GraphicsConfiguration.XVisualInfo2X11Capabilities(..)
  allowing to properly setup the resulting Capabilities instance
  as used in X11GraphicsConfigurationFactory.chooseGraphicsConfigurationImpl(..)

- XVisualInfo:
    - Add 'String toString()'
    - 'XVisualInfo create(XVisualInfo s)' uses source buffer size!
    - XGetVisualInfo: Use returned buffer-capacity/count for element-size
      and also bail out if count<=0
