	<brief_description>
		A custom shader program.
	</brief_description>
	<description>
		This class allows you to define a custom shader program that can be used by a [ShaderMaterial]. Shaders allow you to write your own custom behavior for rendering objects or updating particle information. For a detailed explanation and usage, please see the tutorials linked below.

	<methods>
		<method name="get_default_texture_param" qualifiers="const">
			<return type="Texture2D" />
			<argument index="0" name="param" type="StringName" />
			<description>
				Returns the texture that is set as default for the specified parameter.
				[b]Note:[/b] [code]param[/code] must match the name of the uniform in the code exactly.
			</description>
		</method>
		<method name="get_mode" qualifiers="const">
			<return type="int" enum="Shader.Mode" />
			<description>
				Returns the shader mode for the shader, either [constant MODE_CANVAS_ITEM], [constant MODE_SPATIAL] or [constant MODE_PARTICLES].
			</description>
		</method>
		<method name="has_param" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="name" type="StringName" />
			<description>
				Returns [code]true[/code] if the shader has this param defined as a uniform in its code.
				[b]Note:[/b] [code]param[/code] must match the name of the uniform in the code exactly.
			</description>

		<method name="set_default_texture_param">
			<return type="void" />
			<argument index="0" name="param" type="StringName" />
			<argument index="1" name="texture" type="Texture2D" />
			<description>
				Sets the default texture to be used with a texture uniform. The default is used if a texture is not set in the [ShaderMaterial].
				[b]Note:[/b] [code]param[/code] must match the name of the uniform in the code exactly.
