Neat as it sounds, it will do nothing to help WebGL canvases. In WebGL
applications have full control of the GL viewport which means they need
a way to determine the actual h/w (screen) pixel size of a canvas.
Current methods have many issues some of which are documented in the bug
I referenced in my previous message.
