/** Gets image data, including resolution at all points of use. Call
startGetImageResolution(pdf, min_required_resolution) to begin the process of
obtaining data on all image uses below min_required_resolution, returning the
total number. So, to return all image uses, specify a very high
min_required_resolution. Then, call the other functions giving a serial number
0..n - 1, to retrieve the data. Finally, call endGetImageResolution to clean
up. */
