+// The new ImageBitmapRenderingContext is a canvas rendering context

+  // Displays the given ImageBitmap in the canvas associated with this
+  // rendering context. Ownership of the ImageBitmap is transferred to

+  // after making this call. (This semantic is crucial to enable prompt
+  // reclamation of expensive graphics resources, rather than relying on

+  // The ImageBitmap conceptually replaces the canvas's bitmap, but

+  // The ImageBitmap, when displayed, is clipped to the rectangle
+  // defined by the canvas's instrinsic width and height. Pixels that
+  // would be covered by the canvas's bitmap which are not covered by
+  // the supplied ImageBitmap are rendered transparent black. Any CSS
+  // styles affecting the display of the canvas are applied as usual.
