Resizing the canvas when the viewport is resized.

[vzakharov]

So, it seems that if I start with a smaller viewport and then resize it, the canvas stays in its initial box (as its style's width/height are hardcoded). If I try to override the style settings, the canvas is stretched, but then any zoom events are broken (e.g. zooming on one point actually zooms in a point that's sidewise from the one that should be zoomed on).

Is this a standard problem? Is there a way to fix it?

@vzakharov if you wish to make the component responsive, please look at this other issue: #207
