title: Animate a tint in android via scene transition animation
body: <p>So in my app, I have a scene transition on an image view that transitions it from one activity to another:</p>
  
  <pre><code>v.setOnClickListener(new View.OnClickListener() {
                      @Override
                      public void onClick(View v) {
                          Intent i = new Intent(v.getContext(),tracks.class);
                          i.putExtra("album", al);
                          ActivityOptions transitionActivityOptions = ActivityOptions.makeSceneTransitionAnimation((item_display) v.getContext(), cover, "pic");
                          v.getContext().startActivity(i, transitionActivityOptions.toBundle());
                      }
                  });
  </code></pre>
  
  <p>Now, the scale and positioning transition works fine.  However, on the imageview in the 2nd activity, I have a tint attribute in the xml to make it darker (style choice).  The tint does not animate, so the whole effect is slightly more jarring that I would like.  Is there any way to get the tint to smoothly transition back and forth like the rest of the image?</p>
