When zoom changes occur a resize event is transmitted in many browsers. In order to properly redraw the canvas the windows screen logical DPI x and y data need to spec'd in HTML 5 so as to be consistent across browsers. This will address canvas clarity issues during zooming. 44040 1 ian 2011-01-10 22:22:01 +0000 This is a CSSOM issue.
