		A snippet of shader code to be included in a [Shader] with [code]#include[/code].
	</brief_description>
	<description>
		A shader include file, saved with the [code].gdshaderinc[/code] extension. This class allows you to define a custom shader snippet that can be included in a [Shader] by using the preprocessor directive [code]#include[/code], followed by the file path (e.g. [code]#include "res://shader_lib.gdshaderinc"[/code]). The snippet doesn't have to be a valid shader on its own.
