D2D effect via ID2D1Effect

[aizu03]

It would be nice to use the ID2D1Effect to use the shader effects like Guassian blur. On the Microsoft page it says you can create the effect from the d2d device context.

• Direct2D Effects
• D2D effect apply

m_d2dContext->CreateEffect(CLSID_D2D1GaussianBlur, &gaussianBlurEffect)

I hope this is possible.
