This is a proposal for addition of a zoom-independent version of
window.devicePixelRatio to HTML5. The issue Before Firefox 18 and Chrome 25, to
make a 3D (WebGL) game drawn in HD, we could set the scale in &lt;meta
name="viewport"&gt; to 1 and multiply the size of 2D things (HUD elements,
menus) by window.devicePixelRatio. However, since these versions of the
browsers, devicePixelRatio started to take browser zoom level into account.
While the change works perfectly for loading of high-resolution versions of
&lt;img&gt; images and background-images, it has been impossible to draw HUD
elements in HD 3D games with correct sizes since that.
