GRAPHICS Add a function to copy an image onto another

Somthing like sf::Image::Draw(const Drawable&) ?
We ll have great features, thank you Laurent!

No, that's more something like

sf::Image::Copy(const sf::Image& Source, const sf::IntRect Area, ...)
This one is not very hard to implement, you can already do it by copying pixels in a loop. The main reason for adding it to SFML is to make it faster using internal data rather that GetPixel / SetPixel.

What you're talking about is render-to-image, which is also in the roadmap. This feature is more complex and will take longer to implement.

Nice.

jap rendering to image is a must have.. (btw. would love to see shaders, too)
having RTT + Shaders makes a whole bunch og nice effects possible^^

Shaders will also be part of version 1.4 (you'll still be able to apply a PostFx to a window as a post-fx, but you'll also be able to apply a PostFx to any drawable, more like a regular pixel shader).

great news... any chance on vertexshaders?

A vertex shader for 2D quads ? :|

I could see some uses. Maybe for animating via texture coords. I'm sure it wouldn't be useless, but obviously pixel shaders would be a much bigger deal.
Actually, messing with texture coords is the only thing I can think of off the top of my head.

The more useful part of vertex shaders in SFML would be to have them available for us peeps that use full OGL. It would be pretty useful to have a nicer interface for loading shaders for use in OGL, and it would be interesting to see what people come up with as uses for 2d vertex shaders as well

SFML is meant to be used whether for raw OpenGL rendering or full 2D abstraction ; providing wrapper classes for OpenGL complex features is something which is between both, and I don't think SFML will provide this kind of features in the future.
