     * Process library-specific flags in the open mode string.
     * The following flags may be used to control intrinsic library
     * behaviour that may or may not be desirable (usually for
     * compatibility with some application that claims to support
     * TIFF but only supports some brain dead idea of what the
     * vendor thinks TIFF is):
     *
     * 'l' use little-endian byte order for creating a file
     * 'b' use big-endian byte order for creating a file
     * 'L' read/write information using LSB2MSB bit order
     * 'B' read/write information using MSB2LSB bit order
     * 'H' read/write information using host bit order
     * 'M' enable use of memory-mapped files when supported
     * 'm' disable use of memory-mapped files
     * 'C' enable strip chopping support when reading
     * 'c' disable strip chopping support
     * 'h' read TIFF header only, do not load the first IFD
     * '4' ClassicTIFF for creating a file (default)
     * '8' BigTIFF for creating a file
         * 'D' enable use of deferred strip/tile offset/bytecount array loading.
         * 'O' on-demand loading of values instead of whole array loading (implies D)
     *
     * The use of the 'l' and 'b' flags is strongly discouraged.
     * These flags are provided solely because numerous vendors,
     * typically on the PC, do not correctly support TIFF; they
     * only support the Intel little-endian byte order.  This
     * support is not configured by default because it supports
     * the violation of the TIFF spec that says that readers *MUST*
     * support both byte orders.  It is strongly recommended that
     * you not use this feature except to deal with busted apps
     * that write invalid TIFF.  And even in those cases you should
     * bang on the vendors to fix their software.
     *
     * The 'L', 'B', and 'H' flags are intended for applications
     * that can optimize operations on data by using a particular
     * bit order.  By default the library returns data in MSB2LSB
     * bit order for compatibility with older versions of this
     * library.  Returning data in the bit order of the native CPU
     * makes the most sense but also requires applications to check
     * the value of the FillOrder tag; something they probably do
     * not do right now.
     *
     * The 'M' and 'm' flags are provided because some virtual memory
     * systems exhibit poor behaviour when large images are mapped.
     * These options permit clients to control the use of memory-mapped
     * files on a per-file basis.
     *
     * The 'C' and 'c' flags are provided because the library support
     * for chopping up large strips into multiple smaller strips is not
     * application-transparent and as such can cause problems.  The 'c'
     * option permits applications that only want to look at the tags,
     * for example, to get the unadulterated TIFF tag information.
