| // Helper function which takes a custom thumbnail for the client-side phishing |
| // detector. |
| // |
| // Important note: in some circumstances grabbing a thumbnail using |
| // this function can be very slow since it may need to re-layout the page |
| // twice. Also, using this class may have some side effects (e.g., |
| // onScroll and onResize will be called, etc). Currently, this function |
| // is only used if Chrome is almost certain that the current page is |
| // phishing (according to the client-side phishing detector) in which |
| // case we are not too worried about performance or possibly causing |
| // some JavaScript weirdness on the page. |
