This uses the ResizeObserver devicePixelContentBoxSize API in order to fetch the exact device pixel dimensions from the browser. The old possibly blurry behavior is used as a fallback if that API is not available. Part of #2662 Part of microsoft/vscode#85154

See the full API for more advanced usage.
Handling Context Loss
The browser may drop WebGL contexts for various reasons like OOM or after the system has been suspended. There is an API exposed that fires the webglcontextlost event fired on the canvas so embedders can handle it however they wish. An easy, but suboptimal way, to handle this is by disposing of WebglAddon when the event fires:
const terminal = new Terminal();
const addon = new WebglAddon();
addon.onContextLoss(e => {
addon.dispose();
});
terminal.loadAddon(addon);
