A quick post on how to get the browser to scroll the stage. The simple solution is to draw the stage full size and place it inside a smaller div.
The key here is that the div that contains the canvas has a specified width & height, and also overflow-scroll.
<div id='stagescroll'>
<div id="container"></div>
</div>
#stagescroll
{
width: 800px;
height: 600px;
overflow: scroll;
}
And here is the result.
