Asynchronously loads a pixbuf from the specified file and scales it to the requested width and height. If preserve_aspect_ratio is TRUE, both width and height will always be scaled by the same factor necessary to fit into the specified dimensions. If preserve_aspect_ratio is FALSE, the image will be scaled to be exactly width x height, regardless of aspect ratio (i.e. the image may be compressed or stretched in one direction).

callback : the function to call when the load is complete
user_data : extra data to pass to the callback

file : the GFile that was loaded
result : the GAsyncResult from a GAsyncReadyCallback
error : return location for an error
