  23  * List of macros that should be gathered here:
  24  * 1. all numeric defines used in multiple .cpp or .h files
  25  * 2. all inline functions used in multiple .cpp or .h files
  26  *    and independent enough (do not require other headers)
  27  * 3. class construction macros used in multiple .h files
