* An object that can be drawn to a 2D canvas rendering context.
* The image drawn to the canvas depends on the type of this object:
* * If this object is an [ImageElement], then this element's image is
* drawn to the canvas. If this element is an animated image, then this
* element's poster frame is drawn. If this element has no poster frame, then
* the first frame of animation is drawn.
* * If this object is a [VideoElement], then the frame at this element's current
* playback position is drawn to the canvas.
* * If this object is a [CanvasElement], then this element's bitmap is drawn to
* the canvas.
* **Note:** Currently all versions of Internet Explorer do not support
* drawing a video element to a canvas. You may also encounter problems drawing
* a video to a canvas in Firefox if the source of the video is a data URL.
