<class name="Gradient" inherits="Resource" version="4.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../class.xsd">
	<brief_description>
		A color interpolator resource which can be used to generate colors between user-defined color points.
	</brief_description>
	<description>
		Given a set of colors, this resource will interpolate them in order. This means that if you have color 1, color 2 and color 3, the gradient will interpolate from color 1 to color 2 and from color 2 to color 3. The gradient will initially have 2 colors (black and white), one (black) at gradient lower offset 0 and the other (white) at the gradient higher offset 1.
		See also [Curve] which supports more complex easing methods, but does not support colors.
