      In addition to the image menubar and image right-click menu, you
      can also get the Layers menu by right-clicking on a layer
      thumbnail in the Layers dialog.  Several of the operations in this
      menu are also available from buttons in the Layers dialog:
      resizing a layer, managing layer transparency, and merging layers.

        This dialog comes up when you create a new layer within an
        image.  It is activated by choosing  
        <span class="guimenu">Image</span>-&gt;<span class="guimenuitem">New Layer</span>
      </p>
          <div class="variablelist">

              <dd>
                <p>
              Here you assign the layer a name.  This does not have any
              functional significance:  it is simply a convenience to
              help you remember the role you intended the layer to play
              when you created it.  By default, the name "New Layer" is
              used.  If a layer with this name (or whatever name you
              choose) already exists, after you hit the "OK" button, a
              number will be appended to the name in order to make it
              unique, i. e., "New Layer#1".

              <dd>
                <p>
              Here you set the dimensions of the new layer.  When the
              dialog appears, the values are initialized to the
              dimensions of the image.  You can change them, and if you
              want to use units other than pixels, you can get them
              using the Units menu to the right.  You can't set the
              position of the layer within the image here, but you can
              always move it after it has been created.

              <dd>
                <p>
              Here you have four options for the solid color that will
              fill the layer:  the foreground or background colors as
              shown in the Main Toolbox; white; or transparent.

        of the active layer in all respects but two:  first, if the
        active layer is the bottom layer and lacks an alpha channel, one
        will be added to the copy; second, if any layer parasites are
        attached to the active layer, they are not copied (if you don't
        understand what this means, don't worry about it).

        A layer does not always have same size as the image canvas.  It
        can be smaller (consuming less memory) or larger, in which case
        some parts are hidden.  Selecting this item will activate a
        dialog in which you can set parameters for the layer dimensions:
        these parameters are <span class="guilabel">Width</span> and
        <span class="guilabel">Height</span>, or alternatively <span class="guilabel">Ratio X
        Y</span>.   The layer ratio is maintained if the chain
        symbol has a "locked" appearance. Clicking on the chain symbol
        will toggle it between locked and unlocked states. You can
        use a menu to select the units for the new layer boundary size.
        <span class="guilabel">Offset</span> locates the upper left corner of the
        layer in the image's canvas. In addition to editing the numbers,
        you can change the X and Y offsets by dragging the mouse in the
        interactive image in the dialog. The old layer configuration
        is shown with a blurred border and the new layer
        configuration with a hard border.

        With this item you can resize the
        layer and its contents.  A dialog appears in which you can set
        parameters for the layer size. Those parameters are
        <span class="guilabel">Width</span> and <span class="guilabel">Height</span>
        or also <span class="guilabel">Ratio X Y</span>.  The layer ratio is
        retained if the icon behind the ratio values is a chain.
        When you click on this icon, the chain is broken and the
        original ratio is no longer maintained. You can use a menu to
        select the units for the new layer boundary size.  The
        <span class="guilabel">Interpolation</span> menu let you choose how
        the new layer pixels will be recalculated. When you resize
        the layer content either pixels are added or removed,
        and a recalculation is necessary.  When the new size is
        smaller, the layer is cropped. When the new size is larger, a 
        transparent area (or the background color if the layer has
        no Alpha channel) is added around the previous contents of
        the layer.
