Hi all,

I just wrote a test case which involves applying a CSS image filter
(--webkit-filter or filter) using a grayscale filter.
http://jsfiddle.net/whyn9075/

With this image element, I used a canvas rendering context 2d to drawImage.
Here is the link, http://imgur.com/7OgXEwp, to the screenshot of the
behavior on chrome and FF.

The question is: Should the filter even be applied to the bitmap drawn on
the canvas?

Thank you,
Vivek
