[Request] Stretchy Fullscreen in Browser

Is it possible to have a scaling mode that will squash and stretch the window to fit in any browser dimensions? I am thinking that this will be very useful for creating embedded graphics in adaptive websites. It may even be desired when a device aspect ratio is almost, but not quite, the same as the game ratio. I think that this could be a post-process thing, like Fullscreen scaling...

Would you find that useful? Is it even feasible? Ashley ?

Would you find that useful?

I think it will be very helpful for cases like this.
