-     * Deprecated version that uses one color and two alphas, and supports tonal color.
+     * Helper routine to compute color values for one-pass tonal alpha.
      *
-     * Draw an offset spot shadow and outlining ambient shadow for the given path using a disc
-     * light. The shadow may be cached, depending on the path type and canvas matrix. If the
-     * matrix is perspective or the path is volatile, it will not be cached.
-     *
-     * @param canvas  The canvas on which to draw the shadows.
-     * @param path  The occluder used to generate the shadows.
-     * @param zPlaneParams  Values for the plane function which returns the Z offset of the
-     *  occluder from the canvas based on local x and y values (the current matrix is not applied).
-     * @param lightPos  The 3D position of the light relative to the canvas plane. This is
-     *  independent of the canvas's current matrix.
-     * @param lightRadius  The radius of the disc light.
-     * @param ambientAlpha  The maximum alpha of the ambient shadow.
-     * @param spotAlpha  The maxium alpha of the spot shadow.
-     * @param color  The shadow color.
-     * @param flags  Options controlling opaque occluder optimizations and shadow appearance. See
-     *               SkShadowFlags.
