title: SVGZ (compressed SVG) does not work with ePub readers
body: <p>I was trying to embed compressed SVG file (.SVGZ) to xhtml file of epub like this</p>
  
  <pre><code>&lt;embed class="imageobject" name="297129.sch.001" src="images/out-svgz/297129.sch.001.svgz"/&gt;
  </code></pre>
  
  <p>,when i tested it on various readers,the result was blank space instead of the figures,i know it is a problem of "Content-encoding" which configured on web servers in case of web apps,how can i do the same on my ePub ?</p>
