Vertex Shaders

[OniLinkPlus]

So you have Pixel Shaders working pretty well, I think that you should go ahead and allow us to write our own Vertex Shaders now. It would increase the Flexibility without needing too much to be changed. I am positive someone can find an use for Vertex Shaders in 2D, and if nobody can, then at least we can use gl* 3D Functions with 100% Custom Shaders!

Hi

I already answered to this request:

SFML doesn't aim at providing an abstract layer over OpenGL functions. If something is not relevant for the 2D graphics module, then I won't implement it.
However, providing such a layer is another project that I'll probably think about in the future (when I'll need to make SFML compatible with OpenGL ES, for example).
