/*
* 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.)
