/* Test of file image operations.

​

   The following code provides a means to thoroughly test the file image

   operations. Main objectives are testing operations with multiple open

   images and using all possible flag combinations, which are set in the

   main calling routine. Since the number of open images and flag combinations

   may differ, the flag combinations are assigned to the images in round-robin

   fashion. In order to simulate a realistic operation environment, the code

   operates on as many open objects as possible by using several for-loops

   instead of using a single loop that opens image i, accesses it, and closes

   it. The first loop creates the files and obtains images using the function

   H5Fget_file_image(); two images are set incorrectly (one image is filled

   with "wrong" data while the other image is not valid). The second loop opens

   the images using the function H5LTopen_file_image(), and test whether the

   images have been copied in accordance to the H5LT_FILE_IMAGE_DONT_COPY flag.

   The third loop reads the open images and verifies that the contents are

   correct. The fourth loop first perform writes in the images that do not

   extend the image, and then performs writes that extend the images. The fifth

   loop reads the extended images and verify that the content are correct. The

   sixth and final loop closes the file images and deallocates the image

   buffers if appropriate.                                                   */
