Bug 742 HiDPI: [Core API Change] Distinguish window-units and pixel-units: Refine commit fb57c652fee6be133990cd7afbbd2fdfc084afaa

- NEWT Screen, Monitor, MonitorMode, ..
  - All Units are in pixel units, not window units!

  - On OSX HiDPI, we report the current scaled monitor resolution,
    instead of the native pixel sized.
    Need to filter out those, i.e. report only native unscaled resolutions,
    since out MonitorMode analogy is per MonitorDevice and not per window!

- Fix usage (one by one) of
   - Screen and Monitor viewport usage
