+ * Retrieves the current color of a given texture at given coordinates.
+ *
+ * The given coordinates should be between [0, 0] representing the top-left of
+ * the texture, and [1, 1] representing the bottom-right of the texture.
+ *
+ * The given texture could be, for example:
+ * * <a href="#/p5.Image">p5.Image</a>,
+ * * a <a href="#/p5.Graphics">p5.Graphics</a>, or
+ * * a <a href="#/p5.Framebuffer">p5.Framebuffer</a>.
+ *
+ * The retrieved color that is returned will behave like a vec4, with components
+ * for red, green, blue, and alpha, each between 0.0 and 1.0.
+ *
+ * Linear interpolation is used by default. For Framebuffer sources, you can
+ * prevent this by creating the buffer with:
+ * ```js
+ * createFramebuffer({
+ *     textureFiltering: NEAREST
+ *  })
+ * ```
+ * This can be useful if you are using your texture to store data other than color.
+ * See <a href="#/p5/createFramebuffer/">createFramebuffer</a>.
+ *
+ * Note: The `getTexture` function is only available when using p5.strands.
+ *
+ * @method getTexture
+ * @beta
+ *
+ * @param texture The texture to sample from.
+ * (e.g. a p5.Image, p5.Graphics, or p5.Framebuffer).
+ *
+ * @param coords The 2D coordinates to sample from.
+ * This should be between [0,0] (the top-left) and [1,1] (the bottom-right)
+ * of the texture.  It should be compatible with a vec2.
+ *
+ * @returns {*} The color of the given texture at the given coordinates.  This
+ * will behave as a vec4 holding components r, g, b, and a (alpha), with each component being in the range 0.0 to 1.0.
+ *
+ * @example
+ * <div modernizr='webgl'>
+ * <code>
+ * // A filter shader (using p5.strands) which will
+ * // sample and invert the color of each pixel
+ * // from the canvas.
+ * function setup() {
+ *   createCanvas(100, 100, WEBGL);

+ *   filterColor.set(newColor);
+ *
+ *   filterColor.end();
+ * }
