How to create a new node?

This is a guide that will help with writing new nodes and will help with solving common problems that may occur during the process.

Creating shader nodes

1. Each node needs to inherit from Node class
2. Each node class needs NodeInfoAttribute with Unique Name and Display name, display name should be localized, unique name should be unique across all nodes.
3. Node inputs are serialized and therefore any input should have a proper SerializationFactory class, otherwise saving fails.
4. Run Tests to make sure node doesn't have any obvious issues.

Important notes

1. Do not create new Textures directly unless they are disposed in the same execution context. Creating new textures without managing them properly will lead to memory leaks, performance issues, visual glitches and unexpected crashes.

Use RequestTexture method, it handles node texture caching and management.

2. For the love of god, DO NOT USE SetPixel and GetPixel methods on textures, they are slow and should be avoided at all costs.
