Feature: variable to point out where canvas element must be created

[GoogleCodeExporter]

It could be really useful to have ability to point out which document element 
Engine.getDefaultContext() returns.

Possible solutions: 

* new method Engine.setDefaultContext(DOMElement);
* pass element into Engine.getDefaultContext(DOMElement);

This is not necessary since it is possible to convert an existing element in an 
HTML page into an HTMLElementContext, and then add the CanvasContext to that 
context.  For example:

{{{
// Convert an existing element into a context.  Notice that the second argument
// is the *actual element* and not a jQuery object.  Also note that the Id of
// the element will be assigned the object's Id, overriding any existing 
element Id
var div = R.rendercontexts.HTMLElementContext.create("existingDiv", 
$("div.foo")[0]);
var canvas = R.rendercontexts.CanvasContext.create("playfield", 500, 500);

// Add the canvas to the DIV element
div.add(canvas);

// Make sure the engine knows to update DIV, which will update Canvas
R.Engine.getDefaultContext().add(div);
}}}
