/*
IMAGER_API_VERSION is similar to the version number in the third and
fourth bytes of TIFF files - if it ever changes then the API has changed
too much for any application to remain compatible.
+
+ Version 2 changed the types of some parameters and pointers. A
+ simple recompile should be enough in most cases.
+
+ Version 3 changed the behaviour of some of the I/O layer functions,
+ and in some cases the initial seek position when calling file
+ readers. Switching away from calling readcb etc to i_io_read() etc
+ should fix your code.
+
+ Version 4 added i_psamp() and i_psampf() pointers to the i_img
+ structure.
+
+ Version 5 changed the return types of i_get_file_background() and
+ i_get_file_backgroundf() from void to int.
