Changes in version 1.1.1 (2020-11-13)                  

  - Transparency (alpha channel) can now be used to mask image
    backgrounds. By default, the presence of transparent pixels in a PNG
    overrides other background parameters, and the transparent pixels
    are ignored as background. This behavior can be disabled by setting
    alpha.channel = FALSE in any function that takes an image path as an
    argument.
  - Minor bug fixes with plotting 3D interactive plots.

                 Changes in version 1.1.0 (2019-01-12)                  

Added scatter3dclusters function to plot clusters in color space, scaled
according to their size and colored according to their color.
