	<brief_description>
		Abstract base class for noise generators.
	</brief_description>
	<description>
		This class defines the interface for noise generation libraries to inherit from.
		A default get_seamless_noise() implementation is provided for libraries that do not provide seamless noise. This function requests a larger image from get_image(), reverses the quadrants of the image, then uses the strips of extra width to blend over the seams.
		Inheriting noise classes can optionally override this function to provide a more optimal algorithm.

				Returns a 2D [Image] noise image.
				Note: With [param normalize] set to [code]false[/code] the default implementation expects the noise generator to return values in the range [code]-1.0[/code] to [code]1.0[/code].
