title: difference between Drawee and ImagePipeline in Fresco Image Loading Library
body: <p>I am using Fresco Image Loader in my application in which uri is loaded into <code>SimpleDraweeView</code>. I have a list of images, sometimes i load the same image into two different views. In this case does fresco loads the image from cache into <code>SimpleDraweeView</code> or does it downloads the image from the network whenever needed and also where exactly do i need to use <code>Drawee</code> and <code>ImagePipeline</code>. Please help me.</p>
