/**
 * Class GradientFade
 *
 * Applies a gradient fade effect from one edge of the image.
 *
 * Use ->horizontalStartPoint() for x or ->verticalStartPoint() for y to indicate from which edge to fade and how much
 * of the image should be faded. Values of x and y can be specified as a percentage (Range: 0.0 to 1.0), or in pixels
 * (integer values). Positive values fade from the top (y) or left (x). Negative values fade from the bottom (y) or
 * right (x). By default, the gradient is applied to the top 50% of the image (y = 0.5). Only one direction can be
 * specified but the fade can be applied symmetrically using the mode qualifier. To apply different amounts of fade to
 * multiple edges, use chained fade effects.
