Function snapZoom

snapZoom(zoom: number, tileSize: number, resolution?: number): number
The nearest zoom to zoom at which tileSize * zoom is a whole number of device pixels (resolution device pixels per screen pixel, default 1) - the pure math behind CameraOptions.pixelPerfectTileSize, exported so a game can snap a zoom value (from a slider, say) before ever handing it to a Camera.
Parameters
- zoom: number
- tileSize: number
- resolution: number = 1
Returns number
Example
```
import { snapZoom } from '@datamoc/mwg/two-d/render';

console.log(snapZoom(2.4, 16)); // 2.375 - 16 * 2.375 = 38, a whole number of pixels
```
