title: Carrierwave difference between resizing options
body: <p>I am trying to understand the difference between <code>resize_to_fill</code>, <code>resize_to_fit</code>, and <code>resize_to_limit</code>.</p>
  
  <p>Say I have two images.  Image A is 500x300 and image B is 300x100</p>
  
  <p><code>resize_to_fill</code> 300 x 300<br>
  A - will just slice off 200 pixels of width?<br>
  B - will blow it up to 900x300 and then slice off 600px of width?</p>
  
  <p><code>resize_to_fit</code> 300 x 300<br>
  A - will shrink it down to 300x180?<br>
  B - will not change anything?</p>
  
  <p><code>resize_to_limit</code> -- not sure what the difference between this one and <code>resize_to_fit</code> is..</p>
  
  <p>Can someone explain in a way that's easy to understand?</p>
