Rasterization for fixing offscreen rendering

To fix offscreen rendering issues in overlap containers, use the rasterize extension (iOS only):

{
  "extensions": [
    {
      "id": "rasterize"
    }
  ]
}

The extension has no parameters.

How it works

The element together with its nested elements is rendered as a single bitmap image.
The image is created at the pixel density of the screen, so the content stays sharp.
