Called before the result buffers are drawn to screen. Certain types of aggregations are dependent on render time context and this is alternative opportunity to update just-in-time.

```ts
aggregator.preDraw({moduleSettings: ...});
aggregator.preDraw();
```

Better to clone the project object to avoid mutating it in the calling code?
