 Layers
 ======
 
 These are the topmenu options are related to Layer Management, check out :ref:`that page <layers_and_masks>` first, if you haven't.
 
 Cut Layer (3.0+)
     Cuts the whole layer rather than just the pixels.
 Copy Layer (3.0+)
     Copy the whole layer rather than just the pixels.
 Paste Layer (3.0+)
     Pastes the whole layer if any of the top two actions have been taken.
 New
     Organizes the following actions:
 
     Paint Layer
         Add a new paint layer
     New layer from visible (3.0.2+)
         Add a new layer with the visible pixels.
     Duplicate Layer or Mask
         Duplicates the layer.
     Cut Selection to New Layer
         Single action for cut+paste
     Copy Selection to New Layer
         Single action for copy+paste
 
 Import/Export
     Organizes the following actions:
 
     Save Layer or Mask
         Saves the Layer or Mask as a separate image.
     Save Vector Layer as SVG
         Save the currently selected vector layer as an SVG.
     Save Group Layers
         Saves the top-level group layers as single-layer images.
     Import Layer
         Import an image as a layer into the current file.
     Import as...
         Import an image as a specific layer type. The following layer types are supported:
                 
             * Paint layer
             * Transparency Mask
             * Filter Mask
             * Selection Mask
 
 Convert
     Organizes the following actions:
 
     Convert a layer to...
 
         Convert to Paint Layer
             Convert a mask or vector layer to a paint layer.
         Transparency Mask
             Convert a layer to a transparency mask. The image will be converted to grayscale first, and these grayscale values are used to drive the transparency.
         Filter Mask
             Convert a layer to a filter mask. The image will be converted to grayscale first, and these grayscale values are used to drive the filter effect area.
         Selection Mask
             Convert a layer to a selection mask. The image will be converted to grayscale first, and these grayscale values are used to drive the selected area.
         Convert Group to Animated Layer
             This takes the images in the group layer and makes them into frames of an animated layer.
         Convert Layer Color Space
             This only converts the color space of the layer, not the image.
 
 Select (3.0+):
     Organizes the following actions:
 
     All layers
         Select all layers.
     Visible Layers
         Select all visible layers.
     Invisible Layers
         Select all invisible layers, useful for cleaning up a sketch.
     Locked Layers
         Select all locked layers.
     Unlocked Layers
         Select all unlocked layers.
 
 Group
     Organizes the following actions:
 
     Quick Group (3.0+)
         Adds all selected layers to a group.
     Quick Clipping Group (3.0+)
         Adds all selected layers to a group and adds a alpha-inherited layer above it.
     Quick Ungroup
         Ungroups the activated layer.
 
 Transform
     Organizes the following actions:
 
     Mirror Layer Horizontally
         Mirror the layer horizontally using the image center.
     Mirror Layer Vertically
         Mirror the layer vertically using the image center.
     Rotate
         Rotate the layer around the image center.
     Scale Layer
         Scale the layer by the given amounts using the given interpolation filter.
     Shear Layer
         Shear the layer pixels by the given X and Y angles.
     Offset Layer
         Offset the layer pixels by a given amount.
 
 Split...
     Organizes the following actions:
 
     Split Alpha
         Split the image transparency into a mask. This is useful when you wish to edit the transparency separately.
     Split Layer
         :ref:`Split the layer <split_layer>` into given color fields.
     Clones Array
         A complex bit of functionality to generate clone-layers for quick sprite making. See :ref:`clones_array` for more details.
 
 Edit Metadata
     Each layer can have its own metadata.
 Histogram
     Shows a histogram.
+
+    .. deprecated:: 4.2
