Add script which scales splash screen down

Based on reading documentation around. This particular version
is based on the ImageMagic documentation which could be found
there:

  http://www.imagemagick.org/Usage/filter/
  http://www.imagemagick.org/Usage/filter/nicolas/

Current filter is based on measuring mean error with the current
splash screen and choosing combination of parameters which
gives minimal mean error.
