NativeWindow public* reorg 3/3 ; NativeVisualID -> VisualIDHolder incl. proper utilization.

- VisualIDHolder: Update documentation (Exception case, etc)

- NativeVisualID -> VisualIDHolder (public)
  - incl. generic Comparator
  - better doc and enum values
  - VID_UNDEFINED == 0
  - methods shall not throw exception, but return UNDEFINED

- CapabilitiesImmutable extends VisualIDHolder

- All Capabilties impl.
  - use VID_UNDEFINED for undef. value
  - use final private (immutable) fields

- AbstractGraphicsConfiguration extends VisualIDHolder

- X11 CreateDummyWindow takes (int) visualID
