 Next version
 ============
 
+- make vips_init() into a macro, check sizes of important structs against size
+  at library compile time
+
+  add a new API call like vips__get_sizeof_image() which returns
+  sizeof(VipsImage) from library compile time, compare that to the application
+  compile-time value
+
+  vips_init() macro then passes control on to vips__init() for real startup
+
+  breaks binary API sadly
+
 - do conv and morph quickly as simple wrappers over the vips7 operations
 
 - do much fancier profiling with timing on all locks saved in memory and
