NEWT Soft-PixelScale (p1): WindowImpl: Separate window and pixel units for size and position via atomic-replacable int arrays

NEWT's Soft-PixelScale supports software pixel-scale by multiplying the underlying surface pixel-size with the scale-factor
and dividing the window position and size by same scale-factor.

Hence the window position and size space is kept virtually steady at virtually assumed DPI 96 at higher actual screen DPI
and the surface size is adjusted.

This window- and pixel-unit separation also includes all callbacks for the native driver implementations,
hence the changes native code - allowing to determine whether window- or pixel-units were given.
