[whatwg] Processing the zoom level - MS extensions to window.screen

[Charles Pritchard]

Kevin,

I spoke with a rep on Google TV, as well as a Microsoft IE rep: neither 
saw an active use-case for non-square pixels.

There are cases where width is stretched / squished, but they're always 
handled by scaling the output image. Think of fancy window manager 
effects, and of the ratio selection available on many tvs.

I think the cost of supporting a scaleX and scaleY are minimal; but as 
Robert suggests, the benefits are small. I've brought up the concept of 
a CSS Canvas, based on Robert's comments in this thread, where viewport 
transformations are taken into account by the rending engine.
