	<constants>
		<constant name="SOURCE_TEXTURE" value="0" enum="Source">
			Use the texture given as an argument for this function.
		</constant>
		<constant name="SOURCE_SCREEN" value="1" enum="Source">
			Use the current viewport's texture as the source.
		</constant>
		<constant name="SOURCE_2D_TEXTURE" value="2" enum="Source">
			Use the texture from this shader's texture built-in (e.g. a texture of a [Sprite2D]).
		</constant>
		<constant name="SOURCE_2D_NORMAL" value="3" enum="Source">
			Use the texture from this shader's normal map built-in.
		</constant>
		<constant name="SOURCE_DEPTH" value="4" enum="Source">
			Use the depth texture captured during the depth prepass. Only available when the depth prepass is used (i.e. in spatial shaders and in the forward_plus or gl_compatibility renderers).
		</constant>
		<constant name="SOURCE_PORT" value="5" enum="Source">
			Use the texture provided in the input port for this function.
		</constant>
		<constant name="SOURCE_3D_NORMAL" value="6" enum="Source">
			Use the normal buffer captured during the depth prepass. Only available when the normal-roughness buffer is available (i.e. in spatial shaders and in the forward_plus renderer).
		</constant>
		<constant name="SOURCE_ROUGHNESS" value="7" enum="Source">
			Use the roughness buffer captured during the depth prepass. Only available when the normal-roughness buffer is available (i.e. in spatial shaders and in the forward_plus renderer).
		</constant>
		<constant name="SOURCE_MAX" value="8" enum="Source">
			Represents the size of the [enum Source] enum.
		</constant>
		<constant name="TYPE_DATA" value="0" enum="TextureType">
			No hints are added to the uniform declaration.
		</constant>
		<constant name="TYPE_COLOR" value="1" enum="TextureType">
			Adds [code]source_color[/code] as hint to the uniform declaration for proper sRGB to linear conversion.
		</constant>
		<constant name="TYPE_NORMAL_MAP" value="2" enum="TextureType">
			Adds [code]hint_normal[/code] as hint to the uniform declaration, which internally converts the texture for proper usage as normal map.
		</constant>
		<constant name="TYPE_MAX" value="3" enum="TextureType">
			Represents the size of the [enum TextureType] enum.
