A custom shader program with a visual editor.

<description>
|
|
This class provides a graph-like visual editor for creating a [Shader]. Although [VisualShader]s do not require coding, they share the same logic with script shaders. They use [VisualShaderNode]s that can be connected to each other to control the flow of the shader. The visual shader graph is converted to a script shader behind the scenes.
