Function sharpenText

sharpenText(root: Container, devicePixelRatio: number): void
Re-rasterises every Text under root at devicePixelRatio times its own on-screen scale, rounded to a whole number. Pixi draws text at the renderer's resolution and knows nothing of a parent's zoom, so text inside a scaled container is otherwise 1x text magnified, and blurry. Call it after a layout or zoom change, not every frame; a text already at the right resolution is left untouched.
Parameters
- root: Container
- devicePixelRatio: number
Returns void
Example
```
import { Container } from 'pixi.js';
import { sharpenText } from '@datamoc/mwg/two-d/ui';

const panel = new Container();
panel.scale.set(3);
sharpenText(panel, 2); // every Text inside now rasterises at 6x
```
