api: fix best fit for thumbnail, add background

* fixes for best fit case (f.e. dimensions !400,200) -
  changed variable in the formula

* expected behaviour for best fit case changed
  - now it resizes the image and keeps the ratio of
  an image and fills the background to requested size
  with black pixels - this helps to keep responsive
  images in the UI

* adds the function to fill the pixels with
  black background if the best fit is smaller
  than requested thumbnail box size - preserves
  the thumbnail ratio

* add the function to fill the background with
  black pixels for GIF if the best fit is
  smaller than requested window size

* provides testing cases for portrait, landscape
  and fixed best fit case
