Description Cameron McCormack (:heycam) 2023-03-15 23:53:39 PDT 
Currently with full GPU process enabled, any images we draw will result in ShareableBitmaps that are held on to by the Web process until their owning NativeImage is destroyed.  This decoded image data is often not needed when a tab has gone into the background.  Let's try moving the decoded data into volatile memory once tabs go into the background, to reduce our footprint.
