We've recently made two changes to this API:

1. The API has been renamed drawElementImage (2d) and texElementImage2D (webgl). To make the transition easier, the previous names will continue to work until M145.

2. The privacy&security approach has been updated so that no sensitive information can be drawn into canvas. There was previously an option for this, which has been removed. The explainer has been updated with more information.
