title: How to save canvas as vector image?
body: <p>I'm working on application for designing t-shirts on using <code>fabricjs</code> javascript library. T-shirt template(png) is positioned absolute to canvas. So when the canvas is rasterized to <code>SVG</code>, objects on canvas get saved. </p>
  
  <p>I'm currently storing <code>SVG</code> data on database for displaying purpose. When the process of designing t-shirt is completed, it needs to be saved as vector image so that while zooming, it persists it's original quality. How this can be done? </p>
  
  <p>Or how the system like <a href="http://teespring.com/" rel="nofollow">this</a> saves high quality images?    </p>
