Function fermium::SDL_SetSurfaceRLE

pub unsafe extern "C" fn SDL_SetSurfaceRLE(
    surface: *mut SDL_Surface, 
    flag: c_int
) -> c_int

\brief Sets the RLE acceleration hint for a surface.

\return 0 on success, or -1 if the surface is not valid

\note If RLE is enabled, colorkey and alpha blending blits are much faster, but the surface must be locked before directly accessing the pixels.
