D2D effect via ID2D1Effect

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](https://docs.microsoft.com/en-us/windows/win32/direct2d/effects-overview)
- [D2D effect apply](https://docs.microsoft.com/en-us/windows/win32/direct2d/how-to-apply-effects-to-primitives)

`m_d2dContext->CreateEffect(CLSID_D2D1GaussianBlur, &gaussianBlurEffect)`

I hope this is possible.

Start with the Direct2D Effects and D2D effect apply links in the issue, then inspect the rendering entry point containing m_d2dContext->CreateEffect. Determine the public API and integration needed for ID2D1Effect support; done means a shader effect such as Gaussian blur can be created and applied through the library.
