* Process library-specific flags in the open mode string.
* The following flags may be used to control intrinsic library
* behavior 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 behavior 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.

CreateFileA/CreateFileW return type 'HANDLE' while TIFFFdOpen() takes 'int',
which is formally incompatible and can even seemingly be of different size:
HANDLE is 64 bit under Win64, while int is still 32 bits there.
However, only the lower 32 bits of a HANDLE are significant under Win64 as,
for interoperability reasons, they must have the same values in 32- and
64-bit programs running on the same system, see
https://docs.microsoft.com/en-us/windows/win32/winprog64/interprocess-communication
Because of this, it is safe to define the following trivial functions for
casting between ints and HANDLEs, which are only really needed to avoid
compiler warnings (and, perhaps, to make the code slightly more clear).
Note that using the intermediate cast to "intptr_t" is crucial for warning
avoidance, as this integer type has the same size as HANDLE in all builds.
