 /* SDL stdinc inline functions:
 
-   The theory here is that, by default, we forcibly inline what we can--with
-   real inline functions that avoid macro side-effects--and your app will use
-   the inline version by default. However, we expose a non-inline version
-   too, which internally just wraps the inline version in a real function,
-   so the symbol is always available in the library even if your app
-   bypassed it with the inline version. The SDL_*_inline versions aren't
-   guaranteed to exist, so never call them directly; use SDL_* instead,
-   and trust the system to give you the right thing.
