Mark wrappers of canvas rendering context objects as dependent.
When initially called, canvas.getContext() will return a fresh rendering
context object, but at the same time switch its "context mode" to a direct
one (2d or webgl), such that subsequent getContext() with the same
contextID argument will return that initially created context object.
To correctly provide that same-object identity, the wrapper object must be
marked as depending on the canvas element object, such that it will be
retained across GCs.
