File webkit/glue/multi_resolution_image_resource_fetcher.h (right):

https://chromiumcodereview.appspot.com/10853010/diff/1/webkit/glue/multi_reso...
webkit/glue/multi_resolution_image_resource_fetcher.h:21: class
MultiResolutionImageResourceFetcher{
This is fairly similar to ImageResourceFetcher, but since it calls a different
function in webkit and -- more importantly -- since the callback type is
different, I figured a new file makes more sense.
