-  /**
-  * Returns the Perlin noise value at specified coordinates. Perlin noise is a random sequence
-  * generator producing a more natural ordered, harmonic succession of numbers compared to the
-  * standard random() function. It was invented by Ken Perlin in the 1980s and 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 as demonstrated in
-  * the example above. The 2nd and 3rd dimension 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 difference between coordinates, the
-  * smoother the resulting noise sequence will be. Steps of 0.005-0.03 work best for most applications,
-  * but this will differ depending on use.

-    * Set various hints and hacks for the renderer. This is used to handle obscure rendering features that cannot be
-    * implemented in a consistent manner across renderers. Many options will often graduate to standard features
-    * instead of hints over time.
-    * hint(ENABLE_OPENGL_4X_SMOOTH) - Enable 4x anti-aliasing for OpenGL. This can help force anti-aliasing if
-    * it has not been enabled by the user. On some graphics cards, this can also be set by the graphics driver's
-    * control panel, however not all cards make this available. This hint must be called immediately after the
-    * size() command because it resets the renderer, obliterating any settings and anything drawn (and like size(),
-    * re-running the code that came before it again).
-    * hint(DISABLE_OPENGL_2X_SMOOTH) - In Processing 1.0, Processing always enables 2x smoothing when the OpenGL
-    * renderer is used. This hint disables the default 2x smoothing and returns the smoothing behavior found in
-    * earlier releases, where smooth() and noSmooth() could be used to enable and disable smoothing, though the
-    * quality was inferior.
-    * hint(ENABLE_NATIVE_FONTS) - Use the native version fonts when they are installed, rather than the bitmapped
-    * version from a .vlw file. This is useful with the JAVA2D renderer setting, as it will improve font rendering
-    * speed. This is not enabled by default, because it can be misleading while testing because the type will look
-    * great on your machine (because you have the font installed) but lousy on others' machines if the identical
-    * font is unavailable. This option can only be set per-sketch, and must be called before any use of textFont().
-    * hint(DISABLE_DEPTH_TEST) - Disable the zbuffer, allowing you to draw on top of everything at will. When depth
-    * testing is disabled, items will be drawn to the screen sequentially, like a painting. This hint is most often
-    * used to draw in 3D, then draw in 2D on top of it (for instance, to draw GUI controls in 2D on top of a 3D
-    * interface). Starting in release 0149, this will also clear the depth buffer. Restore the default with
-    * hint(ENABLE_DEPTH_TEST), but note that with the depth buffer cleared, any 3D drawing that happens later in
-    * draw() will ignore existing shapes on the screen.
-    * hint(ENABLE_DEPTH_SORT) - Enable primitive z-sorting of triangles and lines in P3D and OPENGL. This can slow
-    * performance considerably, and the algorithm is not yet perfect. Restore the default with hint(DISABLE_DEPTH_SORT).
-    * hint(DISABLE_OPENGL_ERROR_REPORT) - Speeds up the OPENGL renderer setting by not checking for errors while
-    * running. Undo with hint(ENABLE_OPENGL_ERROR_REPORT).
-    * As of release 0149, unhint() has been removed in favor of adding additional ENABLE/DISABLE constants to reset
-    * the default behavior. This prevents the double negatives, and also reinforces which hints can be enabled or disabled.
