Generally speaking, I took inspiration from material shadows <https://material.io/design/environment/light-shadows.html#>. Pay close attention to pictures in "light and shadows" section.
  
  
  I've looked and while it helped me a little understand what it was meant to achieve, it didn't help me understand how it actually works. I'm not even sure if I can see a difference with and without ambient shadow.
  
  This is Very Large with 100% directional and 0% ambient F6632103: Screenshot_20190223_190524.png <https://phabricator.kde.org/F6632103>
  This is Very Large with 100% directional and 100% ambient F6632107: Screenshot_20190223_190427.png <https://phabricator.kde.org/F6632107>
  
  If the ambient shadow actually did anything, wouldn't the inner areas of the shadow be significantly different in the second screenshot?
