Function splitScreenHalves

splitScreenHalves(
    width: number,
    height: number,
): [
    { height: number; width: number; x: number; y: number },
    { height: number; width: number; x: number; y: number },
]
The two even halves of width×height a two-player split screen typically wants - side by side for a landscape screen, stacked for a portrait one - as plain rectangles a game hands straight to two Viewports (or to resize on a resize event). Not the only reasonable split, so not baked into Viewport itself: a game wanting an L-shaped, uneven, or three/four-player layout lays out its own rectangles the same way.
Parameters
- width: number
- height: number
Returns [
{ height: number; width: number; x: number; y: number },
{ height: number; width: number; x: number; y: number },
]
Example
```
import { splitScreenHalves } from '@datamoc/mw_games/two-d/render';

const [top, bottom] = splitScreenHalves(400, 600); // taller than wide: stacks vertically
console.log(top); // { x: 0, y: 0, width: 400, height: 300 }
console.log(bottom); // { x: 0, y: 300, width: 400, height: 300 }
```
