title: Polygon object support in Backand with an external MySQL
body: <p>I saw a blog post that announced recent filtering support directly through Backand for MySQL points. However, my existing mysql database makes use of the Polygon types as I need to define areas that are more than circular.</p>
  
  <p>At the moment, the Backand syncs the row with a type of String. Is there any way to retrieve my Point objects through the API? Is it possible to decode/encode the strings back into a MySQL Polygon object?</p>
  
  <p>Thank you.</p>
