title: How to make objects without renderer selectable with by click in Unity (editor mode)?
body: <p>I've created my own sprite renderer using Graphics.DrawMesh() and drawing them in editor mode too. Now i facing a problem: I cannot select sprite with mouse. </p>
  
  <p>So the question is: how can I specify bounds of the object, to let the editor knows the area that can be clicked on to select an object?</p>
