title: html2canvas override css (font)
body: <p>I'm using html2canvas javascript library to take a screenshot of my app for feedback functionality purpouses. However my app contains sensitive presonal data that i don't want to be readable on the screenshot. So i've created a font that every glyph looks like a circle (similar to password inputs in IE). My question is:</p>
  
  <p>Is that possible to somehow tell html2canvas to render everything with this font? I have a css rule that applies this to every element on the page. Now i'm adding a css class to <code>body</code> element, then i run html2canvas, and then i remove the class to get original fonts. But for the time of rendering canvas the user can see these strange glyphs and i don't want them to see that.</p>
  
  <p>Any suggestions?</p>
