Implement PrintPageAsJPEG feature for Print Preview.In order to show the tab contents to the print tab, the renderer should print the page as a JPEG image so it could be rendered in the DOMUI. A unit test case has been created to make sure the image contains something from deciding whether its not 100% white.MockPrinter has been altered to remove the const parameter, since its useful to retrieve the DefaultSettings not via IPC.BUG=173 (http://crbug.com/173)TEST=created a unit test and ran it.
