| scrollX | `Element` scrollX | The x-scroll position to used when rendering element, (for example if the Element uses `position: fixed`)
| scrollY | `Element` scrollY | The y-scroll position to used when rendering element, (for example if the Element uses `position: fixed`)

If you wish to exclude certain `Element`s from getting rendered, you can add a `data-html2canvas-ignore` attribute to those elements and html2canvas will exclude them from the rendering.
