+/*
+ * Reading a JPEG file that may contain an ICC profile requires two steps:
+ *
+ * 1. After jpeg_create_decompress() but before jpeg_read_header(),
+ *    ask the IJG library to save in memory any APP2 markers it may find
+ *    in the file.
+ *
+ * 2. After jpeg_read_header(), call jpeg_icc_read_profile() to find
+ *    out whether there was a profile and obtain it if so.
+ *
+ * See if there was an ICC profile in the JPEG file being read;
+ * if so, reassemble and return the profile data.
+ *
+ * TRUE is returned if an ICC profile was found, FALSE if not.
+ * If TRUE is returned, *icc_data_ptr is set to point to the
+ * returned data, and *icc_data_len is set to its length.
+ *
+ * IMPORTANT: the data at **icc_data_ptr has been allocated with malloc()
+ * and must be freed by the caller with free() when the caller no longer
+ * needs it.  (Alternatively, we could write this routine to use the
+ * IJG library's memory allocator, so that the data would be freed implicitly
+ * at jpeg_finish_decompress() time.  But it seems likely that many apps
+ * will prefer to have the data stick around after decompression finishes.)
