Fix broken Offscreen/Pbuffer query introduced in bd4904fb04ab2168aeaf76e74385b3991429289a

    - Have to set the requested values in GLCapabilities if not relaxed and valid,
      otherwise the result is always onscreen, since the onscreen/pbuffer bits
      can be set for the same config.

    - Let GLContext implementations throw an Exception
      in case of no surface handle.

JUnit Tests:
    - MiscUtils.setField -> MiscUtils.setFieldIfExists
      To allow _not_ throwing an exception :)
