Yes, C does not allow manifest constants of anything other than integers 
via enum. Raylib has eschewed most (all?) #defines of integers, 
preferring enums, but e.g. a `Color` struct cannot be an enum.

The pain of having to not only redeclare manifest constants but *also* 
give them a different name is pretty high.
