PR for donnv4 into your v4

[donn-xx]

Paddy,
I don't know why you're so short with me. I can't work out how to chop things into individual commits per node. Instead here is all my work - as clean as I could get it.

There is a change in your examples.tscn, which you can revert/ignore -- I was trying to fix the box and circle demos.

I've done a lot of work and this is the best I can offer you. I hope you can find the patience to pick what you will from the nodes done.

When I see you release some of my nodes, then I'll feel better about making new ones. In the meantime, I won't mutate the donnv4 branch any further.

Best,
/d

Hey Donn, sorry if I come off a bit rough. It's important for me to have little overhead when others want to contribute to my addons. I don't have much time on my hands so having a good PR which in details explains already the changes that were added in the PR description, doesn't contain too much content for me to review and which keeps a similar/ the same structure I already built up takes a lot off my plate
I am very thankful for your contribution and I hope you won't abandon open-source but please get more familiar with git and GitHub when contributing through these tools. Granted, I don't have a Contributor's Guide but for many other open-source projects basic knowledge in Git and GitHub is required. Now for the structure of my addons: In the beginning you completely disregarded the structure I built up. Naming your demo folder after yourself falls in the same category but I get your sentiment of giving me an overview. However if you filled out the description of your PR and kept your PRs smaller like I suggested, this would be much smaller. Please keep that in mind for the future and please correct this when you read this. By description I mean a list of the Nodes you added, their effects/use-case and screenshots. To keep these showcases small and embed them in clickable sections, please refer to this guide: https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/organizing-information-with-collapsed-sections

Now about your changes. The nodes and example scene that I think are usable because they effectively show the effects are:

• blur_2d_demo
• color_mask_2d_demo
• normalmap_z_3d_demo
• pmap_3d_demo
• hexagonal_demo
• Smooth Box (only inside the already available Shapes showcase -> not their own demo)
• Smooth Circle (only inside the already available Shapes showcase) -> not their own demo
• texture_stack_3d_demo
• tiler_2d_demo -> should be renamed to brick_tiler
• wn_mask_demo
• wn_mixer_demo

If you read this comment and still want to work on this, give it a 👍🏻 as a reaction and I will delete it. I implore you as well to clean the description of your PR and add the description of your changes like described above.
