-	 * 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 braindead 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
-	 *
-	 * 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 compatibiltiy 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.
