Bug 1120 - Refine HiDPI Support ( Part-2 ) (API CHANGE)

- Use float[2] for pixel-scale.
  Utilize simple integer rounding:
    int-pixel-units = (int) ( int-window-units * pixel-scale + 0.5f )

- Provide minimum and maximum allowed pixel-scale values
  to be set by platform, supporting generic pixel-scale validation.

- Remove 'OSXUtil.GetPixelScale(final RectangleImmutable r, final int[] screenIndexOut)',
  implementation for all platforms would cause huge redundancy of
  Screen and MonitorDevice code (duplication of NEWT).

- instead, add 'float[2] pixelScale' to NEWT's MonitorDevice

- Detect change of pixel-scale and propagate accordingly.
  This allows GLCanvas, GLJPanel and NewtCanvasAWT instances
  to be dragged between monitor devices w/ different pixel-scale.

- OSX: Handle native triggered reshape events off-thread to avoid EDT congestion
       due to locked window when consuming deferred events on EDT.
