/*
* This is an advanced writing function that must be used in a particular
* sequence, and generally together with TIFFForceStrileArrayWriting(),
* to make its intended effect. Its aim is to modify the location
* where the [Strip/Tile][Offsets/ByteCounts] arrays are located in the file.
* More precisely, when TIFFWriteCheck() will be called, the tag entries for
* those arrays will be written with type = count = offset = 0 as a temporary
* value.
*
* Its effect is only valid for the current directory, and before
* TIFFWriteDirectory() is first called, and will be reset when
* changing directory.
*
* The typical sequence of calls is:
* TIFFOpen()
* [ TIFFCreateDirectory(tif) ]
* Set fields with calls to TIFFSetField(tif, ...)
* TIFFDeferStrileArrayWriting(tif)
* TIFFWriteCheck(tif, ...)
* TIFFWriteDirectory(tif)
* ... potentially create other directories and come back to the above directory
* TIFFForceStrileArrayWriting(tif): emit the arrays at the end of file
*
* Returns 1 in case of success, 0 otherwise.
