Description Kimmo Kinnunen 2023-07-06 03:12:37 PDT 
Remote image buffer Context2D contexts are prepared needlessly

The preparation step prepares for external access of the ImageBuffer backing store.
The Context2D does not use external access for compositing, rather the image buffer is just drawn to another image buffer.
