Despite there is lot of work ahead I today I have achieved the two main objectives I aimed with this project:
1. Being able to reuse VapourSynth plugins 2. Being able to create pure Nim filters in an easy way. And [this](https://github.com/mantielero/VapourSynth.nim/blob/447f3cda3185cacca593f760d38c298fea1f6b2e/src/filters/croprel.nim) is my first working example. I have created a post in [doom9](https://forum.doom9.org/showthread.php?p=1905351#post1905351). I hope this brings more visibility to Nim as well.
