+////////////////////////////////////////////////////////////
+/// \class sf::StencilMode
+/// \ingroup graphics
+///
+/// sf::StencilMode is a class that controls stencil testing.
+///
+/// In addition to drawing to the visible portion of a render target,
+/// there is the possibility to "draw" to a so-called stencil buffer.
+/// The stencil buffer is a special non-visible buffer that can contain
+/// a single value per pixel that is drawn. This can be thought of as a
+/// fifth value in addition to red, green, blue and alpha values. The maximum
+/// value that can be represented depends on what is supported by the system.
+/// Typically support for a 8-bit stencil buffer should always be available.
+/// This will also have to be requested when creating a render target via
+/// the sf::ContextSettings that is passed during creation. Stencil testing
+/// will not work if there is no stencil buffer available in the target
+/// that is being drawn to.
+///
+/// Initially, just like with the visible color buffer, the stencil value of
+/// each pixel is set to an undefined value. Calling sf::RenderTarget::clear
+/// will set each pixel's stencil value to 0. sf::RenderTarget::clear can be
+/// called at any time to reset the stencil values back to 0.
+///
+/// When drawing an object, before each pixel of the color buffer is updated
+/// with its new color value, the stencil test is performed. During this test
+/// 2 values are compared with each other: the reference value that is passed
+/// via sf::StencilMode and the value that is currently in the stencil buffer.
+/// The arithmetic comparison that is performed on the 2 values can also be
+/// controlled via sf::StencilMode. Depending on whether the test passes i.e.
+/// the comparison yields true, the color buffer is updated with its new RGBA
+/// value and if set in sf::StencilMode the stencil buffer is updated
+/// accordingly. The new stencil value will be used during stencil testing the
+/// next time the pixel is drawn to.
+///
+/// The class is composed of 4 components, each of which has its
+/// own public member variable:
+/// \li Stencil Comparison (@ref stencilComparison)
+/// \li Stencil Update Operation (@ref stencilUpdateOperation)
+/// \li Stencil Reference Value (@ref stencilReference)
+/// \li Stencil Mask Value (@ref stencilMask)
+/// \li Stencil Only Update (@ref stencilOnly)
+///
+/// The stencil comparison specifies the comparison that is performed between
+/// the reference value of the currently active sf::StencilMode and the value
+/// that is currently in the stencil buffer. This comparison determines whether
+/// the stencil test passes or fails.
+///
+/// The stencil update operation specifies how the stencil buffer is updated if
+/// the stencil test passes. If the stencil test fails, neither the color or
+/// stencil buffers will be modified. If incrementing or decrementing the
+/// stencil value the new value will be clamped to the range from 0 to the
+/// maximum representable value given the bit width of the stencil buffer
+/// e.g. 255 if an 8-bit stencil buffer is being used.
+///
+/// The reference value is used both during the comparison with the current
+/// stencil buffer value and as the new value to be written when the operation
+/// is set to Replace.
+///
+/// The mask value is used to mask the bits of both the reference value and
+/// the value in the stencil buffer during the comparison and when updating.
+/// The mask can be used to e.g. segment the stencil value bits into separate
+/// regions that are used for different purposes.
+///
+/// In certain situations, it might make sense to only write to the stencil
+/// buffer and not the color buffer during a draw. The written stencil buffer
+/// value can then be used in subsequent draws as a masking region.
+///
+/// In SFML, a stencil mode can be specified every time you draw a sf::Drawable
+/// object to a render target. It is part of the sf::RenderStates compound
+/// that is passed to the member function sf::RenderTarget::draw().
+///
+/// \see sf::RenderStates, sf::RenderTarget
