  // Note on CSS files from Benjamin Shell:
  // Stylesheets are a problem with image assist. Image assist works great as a
  // TinyMCE plugin, so I want it to LOOK like a TinyMCE plugin. However, it's
  // not always a TinyMCE plugin, so then it should like a themed Drupal page.
  // Advanced users will be able to customize everything, even TinyMCE, so I'm
  // more concerned about everyone else. TinyMCE looks great out-of-the-box so I
  // want image assist to look great as well. My solution to this problem is as
  // follows:
  // If this image assist window was loaded from TinyMCE, then include the
  // TinyMCE popups_css file (configurable with the initialization string on the
  // page that loaded TinyMCE). Otherwise, load drupal.css and the theme's
  // styles. This still leaves out sites that allow users to use the TinyMCE
  // plugin AND the Add Image link (visibility of this link is now a setting).
  // However, on my site I turned off the text link since I use TinyMCE. I think
  // it would confuse users to have an Add Images link AND a button on the
  // TinyMCE toolbar.
  // 
  // Note that in both cases the img_assist.css file is loaded last. This
  // provides a way to make style changes to img_assist independently of how it
  // was loaded.
