   4 Subject: [PATCH 34/38] doze: allow grayscale even if invert boolean is false
   5
   6 for dark themes, we are setting the config boolean for inverting
   7     doze notifications to false.  in addition to preventing
   8     color inversion, this was also preventing the notification
   9     from grayscaling.  as a result, on dark themes (boolean false), we
  10     were seeing color icons on doze notifications.  this commit fixes
  11     the grayscaling, and brings back the very aesthetically pleasing
  12     (imo) grayscale-to-color fade-in for the notifications' app icons.
