10 IMAGER_API_VERSION is similar to the version number in the third and
11 fourth bytes of TIFF files - if it ever changes then the API has changed
12 too much for any application to remain compatible.

14 Version 2 changed the types of some parameters and pointers. A
15 simple recompile should be enough in most cases.

17 Version 3 changed the behaviour of some of the I/O layer functions,
18 and in some cases the initial seek position when calling file
19 readers. Switching away from calling readcb etc to i_io_read() etc
20 should fix your code.

22 Version 4 added i_psamp() and i_psampf() pointers to the i_img
23 structure.
