Shaders?

[googleman]

I was pondering about this for a while now. Will Graal ever support shaders? If you ever played Half-Life 2, you would have seen the little neat shader used with a sprite when a strider fires the cannon. It bends the render in and looks as if it's sucking in everything around it. I always wanted to achieve something like that in Graal. So would that be a possibility in the future?
