OK. If it says 2.0.5, then you do have it installed. And I'm out 
of ideas until I try it out myself.

Some of the functions listed on the SDL Wiki, like this one [1], 
have at the bottom of the page the version they were added. But 
it's easier to look at the source for DerelictSDL2. In order to 
support the SharedLibVersion, the loader implements functions 
like this one:

```
private ShouldThrow allowSDL_2_0_0(string symbolName) {
       switch(symbolName) {
             // Functions added in 2.0.1
             case "SDL_free": break;
             case "SDL_SetAssertionHandler": break;
             case "SDL_GetAssertionReport": break;
             case "SDL_ResetAssertionReport": break;
             case "SDL_GetSystemRAM": break;
             case "SDL_UpdateYUVTexture": break;
             case "SDL_GL_GetDrawableSize": break;
             case "SDL_GetBasePath": break;
             case "SDL_GetPrefPath": break;
             default: return allowSDL_2_0_1(symbolName);
       }
       return ShouldThrow.No;
}
```

So you can look starting from [2] to see all of the functions 
added in 2.0.1 and higher.
