Simple example of using DOMElement to position HTML content
within the EaselJS display list. Note how the black
DOMElement can display outside the canvas boundaries,
whereas the red Shape cannot.
Hello! I'm an HTML div.
I am not rendered to the canvas, but I can be included in the display
list for positioning and transformations.
This means I can contain any HTML content (rich text, forms, video,
etc), but I'm not a full part of the EaselJS display list.
