\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.
