title: How to add touch effect to TRectangle in Delphi Firemonkey / Android app?
body: <p>I want to add touch effect animation (expanding circe) to a <code>TRectangle</code>. Same kind of effect that is present on <code>TButtons</code> by default - when you put a finger on them they start to draw expanding circle.</p>
  
  <p>I'm looking for the simplest way of doing so, preferrably in the FMX (e.g. take some component from component palette, add it to <code>Rect1</code> and configure), not in code.</p>
  
  <p>Why not use custom <code>TButton</code>? Well, I'm looking to use only this touch effect and don't need any of the additional button properties / methods.</p>
