+\file MacroMagic.h
+
+This file allows the same macros to do multiple duty by undefining 
+and redefining the macros.
+
+For example DEFINE_IMAGE will generate:
+
+  - extern int name;
+  - int name = -1;
+  - RegisterImage( name, initiialiser, textual_name);
+
+On three different passes.  We control which by defining one of
+THEME_INITS or THEME_DECLARATIONS or neither of these.
