I just use it to convert an image to jpeg and scale it to a fixed size, 
or to generate a jpeg image with a text in it.
The use case is to manage user's avatars from a web application, if an 
image is provided then it's used as the avatar, otherwise a dummy avatar 
is generated with the user's initials.

I understand that, what I don't understand is why I didn't need it with 
lazarus 2.0.12 (and why the program could be build with gtk2 even 
without the interfaces unit).

That's why I'm not really comfortable with it, though it seems to be 
enough for this application.
