Bug 1374: NEWT/AWT: Annotation regarding general High-DPI for even non native DPI toolkit aware platforms (Linux, Windows)

NEWT + NewtCanvasAWT:

Maybe create "interface ScalableSurface.Upstream {
  void pixelScaleChangeNotify(final float[] curPixelScale, final float[] minPixelScale, final float[] maxPixelScale); }"

to allow downstream to notify upstream ScalableSurface implementations like NEWT's Window to act accordingly.

AWT GLCanvas: Add remark where to add the potential pixel scale.
