Add 'DirectDataBufferInt' supporting NIO based BufferedImages

- Contains convenient method to create an NIO backed BufferedImage
  'BufferedImage createBufferedImage(int width, int height, int numComponents, Point location)'

Standalone test TestTiledPrintingNIOImageSwingAWT 'prints', i.e. renders offscreen,
the Frame into
  - a traditional array-backed BufferedImage
  - an NIO-backed backed BufferedImage
