I think something like the following, but maybe you know better.
(function() {
var oldCloneNode = HTMLCanvasElement.prototype.cloneNode;
HTMLCanvasElement.prototype.cloneNode = function(deep) {
var copy = oldCloneNode.call(this, deep);
var copy_ctx = copy.getContext("2d");
copy_ctx.drawImage(this, 0, 0, this.width, this.height);
return copy;
};
})();
Looks right to me, though generally I would discourage this style of
programming as it makes it quite hard for people to maintain unless they
are very familiar with the codebase.
OK. Thanks
