title: Svelte component onLoad
body: <p>Is there a way to know when a Svelte component has finished loading all its external resources, rather than <code>onMount</code>?</p>
  <p>It is similar to the <code>onload</code> event of <code>window</code>.</p>
  <p>EDIT: To clear things up, I would like a component to do something after it fully loads all its images.</p>
  <p>EDIT2: I decided to use javascript to load images. In my opinion, this is not the cleanest way to do things, but it works.
  Thank you!</p>
