## Test Plan

Examples app -> Filters -> FeComposite

## Compatibility

| OS      | Implemented |
| ------- | :---------: |
| iOS     |    ✅      |
| macOS   |    ❌*      |
| Android |    ✅      |
| Web     |    ✅      |

_*_ macOS isn't working as:
* `CGBitmapContextCreateImage` always returns null
* FeFlood isn't aligned properly (will be fixed in the following PR)
