Adding Blur to Cube Meshes?

[collinskatie]

Hi redner team,

Thank you for such an awesome library!

Similar to Question #149, I was wondering if there's a natural way to add blur to a mesh? Or the best way to use a soft rasterizer (as proposed in https://openaccess.thecvf.com/content_ICCV_2019/papers/Liu_Soft_Rasterizer_A_Differentiable_Renderer_for_Image-Based_3D_Reasoning_ICCV_2019_paper.pdf) Just wanted to check if there's a straightforward way to implement a learnable blur/blending in redner?

Thanks for any help and/or advice!
