I have to specify very unusual blend mode (DestAlpha) for custom object derived from sf::drawable and I don't want to recompile entire SFML (because it will break down in next SFML update). Is there any way to do this without such recompillation (like writing custom OpenGL code?). Just as side note - I am drawing object which don't have textures, only colors.
Do not follow where the path may lead — go instead where there is no path and leave a trail.

You can use the full power of OpenGL with SFML. How you actually do it, is a different question and since I've no knowledge in OpenGL I can't answer it. ;)

I don't have much knowledge in OpenGL either, so I need some directions :)

You won't be able to render an SFML object with a custom OpenGL blend mode. If you go the OpenGL way, you must handle everything with it.

Why not just clone the repo and keep your personal branch with additional blend modes? Unless Laurent completely breaks the blending code you should be able to keep up with master just fine.
