**Summary**
[HJG]: Inspired by [Xmas Tree] from [RS], here is a version where you can decorate the tree yourself.

   * Use option-menus to select color and type of decoration
   * Click on canvas to place it
   * Right-click to remove an item
   * F1 to show console
   * Cut+paste your design from the console-log to the proc Decorate
   * Save program + restart it

The candles are animated with a bit of flickering.

Merry Christmas !
