+    but note that with the depth buffer cleared, any 3D drawing that
+    happens later in draw will ignore existing shapes on the screen.
+
+  :enable-depth-test - Enables the zbuffer.
+
+  :enable-depth-sort - Enable primitive z-sorting of triangles and

+    performance considerably, and the algorithm is not yet perfect.
+
+  :disable-depth-sort - Disables hint :enable-depth-sort

+  been used since in graphical applications to produce procedural
+  textures, natural motion, shapes, terrains etc.
+
+  The main difference to the random function is that Perlin noise is
+  defined in an infinite n-dimensional space where each pair of
+  coordinates corresponds to a fixed semi-random value (fixed only for
+  the lifespan of the program). The resulting value will always be
+  between 0.0 and 1.0. Processing can compute 1D, 2D and 3D noise,
+  depending on the number of coordinates given. The noise value can be
+  animated by moving through the noise space and the 2nd and 3rd
+  dimensions can also be interpreted as time.
+
+  The actual noise is structured similar to an audio signal, in
+  respect to the function's use of frequencies. Similar to the concept
+  of harmonics in physics, perlin noise is computed over several
+  octaves which are added together for the final result.
+
+  Another way to adjust the character of the resulting sequence is the
+  scale of the input coordinates. As the function works within an
+  infinite space the value of the coordinates doesn't matter as such,
+  only the distance between successive coordinates does (eg. when
+  using noise within a loop). As a general rule the smaller the

+                     want to enable present mode - :features [:present]
+
+   :renderer       - Specifies the renderer type. One of :p2d, :p3d, :java2d,
+                     :opengl, :pdf). Defaults to :java2d. :dxf renderer
+                     can't be used as sketch renderer. Use begin-raw method
+                     instead. In clojurescript only :p2d and :p3d renderers
+                     are supported.
+
+   :output-file    - Specifies an output file path. Only used in :pdf mode.
+                     Not supported in clojurescript.
+
+   :title          - A string which will be displayed at the top of
+                     the sketch window. Not supported in clojurescript.
+
+   :features       - A vector of keywords customizing sketch behaviour.
+                     Supported features:
+
+                     :keep-on-top - Sketch window will always be above other
+                                    windows. Note: some platforms might not
+                                    support always-on-top windows.
+                                    Not supported in clojurescript.
+
+                     :exit-on-close - Shutdown JVM  when sketch is closed.
+                                      Not supported in clojurescript.
+
+                     :resizable - Makes sketch resizable.
+                                  Not supported in clojurescript.
+
+                     :no-safe-fns - Do not catch and print exceptions thrown
+                                    inside functions provided to sketch (like
+                                    draw, mouse-click, key-pressed and
+                                    other). By default all exceptions thrown
+                                    inside these functions are catched. This
+                                    prevents sketch from breaking when bad
+                                    function was provided and allows you to
+                                    fix it and reload it on fly. You can
+                                    disable this behaviour by enabling
+                                    :no-safe-fns feature.
+                                    Not supported in clojurescript.
+
+                     :present - Switch to present mode (fullscreen without
+                                borders, OS panels). You may want to use
+                                this feature together with :size :fullscreen.
+                                Not supported in clojurescript.
+
+                     :no-start - Disables autostart if sketch was created using
+                                 defsketch macro. To start sketch you have to
+                                 call function created defsketch.
+                                 Supported only in clojurescript.
+
+                     :global-key-events - Allows a sketch to receive any
+                                          keyboard event sent to the page,
+                                          regardless of whether the canvas it is
+                                          loaded in has focus or not.
+                                          Supported only in clojurescript.
+
+                     Usage example: :features [:keep-on-top :present]
+
+   :bgcolor        - Sets background color for unused space in present mode.
+                     Color is specified in hex format: #XXXXXX.
+                     Example: :bgcolor \"#00FFFF\" (cyan background)
+                     Not supported in clojurescript.
+
+   :display        - Sets what display should be used by this sketch.
+                     Displays are numbered starting from 0. Example: :display 1.
+                     Not supported in clojurescript.
+
+   :setup          - A function to be called once when setting the sketch up.
+
+   :draw           - A function to be repeatedly called at most n times per
+                     second where n is the target frame-rate set for
+                     the visualisation.
+
+   :host           - String id of canvas element or DOM element itself.
+                     Specifies host for the sketch. Must be specified in sketch,
+                     may be omitted in defsketch. If ommitted in defsketch,
+                     :host is set to the name of the sketch. If element with
+                     specified id is not found on the page and page is empty -
+                     new canvas element will be created. Used in clojurescript.
+
+   :focus-gained   - Called when the sketch gains focus.
+                     Not supported in clojurescript.
+
+   :focus-lost     - Called when the sketch loses focus.
+                     Not supported in clojurescript.

+
+   :mouse-exited   - Called when the mouse leaves the sketch window
+
+   :mouse-pressed  - Called every time a mouse button is pressed.
+
+   :mouse-released - Called every time a mouse button is released.
+
+   :mouse-clicked  - called once after a mouse button has been pressed
+                     and then released.
+
+   :mouse-moved    - Called every time the mouse moves and a button is
+                     not pressed.
+
+   :mouse-dragged  - Called every time the mouse moves and a button is
+                     pressed.
+
+   :mouse-wheel    - Called every time mouse wheel is rotated.
+                     Takes 1 argument - wheel rotation, an int.
+                     Negative values if the mouse wheel was rotated
+                     up/away from the user, and positive values
+                     if the mouse wheel was rotated down/ towards the user
+
+   :key-pressed    - Called every time any key is pressed.
+
+   :key-released   - Called every time any key is released.
+
+   :key-typed      - Called once every time non-modifier keys are
+                     pressed.
+
+   :on-close       - Called once, when sketch is closed
+                     Not supported in clojurescript.
+
+   :middleware     - Vector of middleware to be applied to the sketch.
+                     Middleware will be applied in the same order as in comp
+                     function: [f g] will be applied as (f (g options)).
+
+   :settings       - cousin of :setup. A function to be called once when
+                     setting sketch up. Should be used only for (smooth) and
+                     (no-smooth). Due to Processing limitations these functions
+                     cannot be used neither in :setup nor in :draw."
