-   * When trying to get an image frame of a DRM-protected video in
-   * firefox, the method canvas.drawImage(video) will throw an exception.

-   * This doesn't happen in Chrome. As opposed to Firefox, chrome will
-   * simply draw a transparent black image and not tell anyone that
-   * anything is amiss. However, since the image is (according to my testing
-   * on netflix) completely transparent, this means we can determine whether
-   * the video is DRM-protected by looking at the alpha byte of the image.
-   * 
-   * (Videos don't tend to have an alpha channel, so they're always
-   * completely opaque (i.e. have value of 255))
