To answer the question in your subject, “Very Carefully.”
While I don’t know much about your particular problem domain (and it seems
others have given useful advice), I can say some general things about
making mutable things immutable.
There is a very simple way to make something mutable immutabl
Okay,
so I think that the better idea is to carry on with my low-level, imperative
binding, and then build a more functional on top of this.
Concerning the mutability of images, I notice that the problem with SFML is
that it handles Sprites in a way that is even more imperative than OpenGL

In fact, I would like to determine if an EFFICIENT way to make images and
such immutable exists, or if it is impossible
I think it might influence performance, but it doesn't have to be that much.
There are some optimization tricks you can apply to deal with this. Premature
optimization is the root of all evil ;)

Making an immutable API from a mutable one generally damages
performance (on von neumann architectures) somewhat, the goal is to
minimize that impact.
Cheers.

That's indeed an advice I've read [1].
But wouldn't it damage the performances, since code will have to go through
an extra layer?

Check out graphics-drawingcombinators.

Hello,
I don't know if some of you are familiar with the SFML library (stands for
Simple and Fast Multimedia Library) --> http://sfml-dev.org
As SDL, SFML is a 2D graphics library, but conversely to SDL it provides a
hardware-accelerated drawing, through OpenGL.
Well, I'm currently writing its Has
