 /** This class overrides all virtual methods on SkCanvas, and redirects them
     to a "proxy", another SkCanvas instance. It can be the basis for
     intercepting (and possibly modifying) calls to a canvas.
 
     There must be a proxy installed before the proxycanvas can be used (i.e.
     before its virtual methods can be called).
