Pure golang image resizing

The resize package provides 2 functions: - resize.Resize creates a scaled image with new dimensions

  (width, height) using the interpolation function interp.
  If either width or height is set to 0, it will be set to
  an aspect ratio preserving value.

- resize.Thumbnail downscales an image preserving its aspect

  ratio to the maximum dimensions (maxWidth, maxHeight).  It
  will return the original image if original sizes are smaller
  than the provided dimensions.
