JavaScript Image Resize: Rescale images smoothly using HTML canvas objects

This object can rescale images smoothly using HTML canvas objects.

It can take an image given the image object or a selector string of the image element to rescale.

The object can create a canvas to render the image rescaled to a given ratio or to a given size optionally preserving the original image proportions.

The image can be rescaled smoothly if the browser supports the imageSmoothingEnabled property. The smoothing level is configurable.

The object calls a given callback function when the rescaling is done passing the canvas object that contains the rescaled image.
