 We need a mechanism to make GRHydro_Macros.h usable by other thorns and
 especially other languages. If used as is currently I cannot write an
 extra thorn setting things to atmosphere conforming to these new
 parameters - especially not in C, unless I essentially re-implement the
 logic - which would be bad code-duplication. This was no issue so far
 because the logic was so simple. With this patch this would no longer be
 true.
