DngCreator: scale lens distortion paramters

To create a zoom effect on rendered DNG such that all pixels on
the rendered image is sampled within the precorrection array of
input RAW image.

Test: check DNG output on pixel 3 (and also an exaggerated lens
      distortion coefficients that scale up the image almost 2x)
