/**
* To use the dynamic libtiff support, you must initialize the library using:
* libtiff_init()
* This attempts to load libtiff dynamically at runtime. G.have_libtiff will
* be set to indicate whether or not libtiff is available. If libtiff is
* not available, Blender can proceed with no ill effects, provided that
* it does not attempt to use any of the libtiff_ functions. When you're
* finished, close the library with:
* libtiff_exit()
* These functions are both declared in IMB_imbuf.h
*
* The functions provided by dyn_libtiff.h are the same as those in the
* normal static / shared libtiff, except that they are prefixed by the
* string "libtiff_" to indicate that they belong to a dynamically-loaded
* version.
