Description

Created:

• AsciiEffect (to improve), I took the effect from there and transferred it to the new file, so you can do refactor and figure out what you can add.
• Ascii Content Page, inserted the preview scene and put in alphabetical order.
• Ascii Demo (to fix), I created the file also for the demo but maybe it’s a bit early, in case it is not useful at the moment you can easily delete it.

Thanks! I'll take it from here.

If you have contribution guidelines I can try to improve the code and make it consistent with the library.

I can also try to understand how the other effects are managed, I will try to contribute as I can

The contribution guide can be found here.

There's not much that needs to be changed here apart from some linting and refactoring. I'm short on time and it's faster for me to do the clean up myself, but thanks for offering help. Also, optimizing the shader requires active debugging which isn't really doable through PR comments.

You can check out the concepts in v7 through the existing effects and then try your hand at porting this effect to v7 once I'm done with the refactoring. I'll create a new ticket for that task.
