Mixing libraries

[Jordan Wilson via Digitalmars-d-learn]

Hello,

Been trying to learn the Simple Fast Multimedia Library (SFML) 
using the Derelict bindings, and noticed some functionality is 
offered by both SFML and the std library (for example, sfClock 
and sfMutex).

Is there a general design principle of, say, use the std library 
whenever possible and only SFML when I have too? Or should I try 
to be consistent and use SFML library whenever possible?

Thanks,

Jordan
