  95.       This filter uses the current gradient, as shown in the
  96.       Brush/Pattern/Gradient area of the Toolbox, to recolor the active
  97.       layer or selection of the image to which the filter is applied. To
  98.       use it, first choose a gradient from the <a class="link" href="gimp-gradient-dialog.html" title="3.4.¬† Gradients Dialog">Gradients Dialog</a>.
  99.       Then select the part of the image you want to alter, and activate the
  100.       filter. The filter runs automatically, without
  101.       showing any dialog or requiring any further input.   It uses image
  102.       color intensities (0 - 255), mapping the darkest pixels to
  103.       the left end color from the gradient, and the lightest pixels to
  104.       the right end color from the gradient. Intermediate values are set
  105.       to the corresponding intermediate colors.
