+   * with plugin configuration fields.
+   * <br><br>
+   *
+   * Plugins names and documentation about each plugin could be found here:
+   * {@link DrawerJs.plugins}.
+   * Look at plugin's constructor `<code>options</code>` argument.
+   * <br><br>
+   *
+   * For example we would like to configure
+   * {@link DrawerJs.plugins.Text} and {@link DrawerJs.plugins.Eraser}
+   * plugins:
+   * <code><pre class="prettyprint">
+   * pluginsConfig: {
+   *   "Text": {

+   *   }
+   * }
+   * </code></pre>

+   * @param {Object} options.defaultActivePlugin
+   * Activates default tool, if options.defaultActivePlugin is set;
+   * MUST contain keys:
+   * name - name of plugin
+   * mode - one of : ['always', 'onNew', 'lastUsed']
+   * Depending on options.defaultActivePlugin.mode :
+   * 'always'   - same plugin will be always actived
+   * 'onNew'    - default plugin is actiavted, only if canvas is empty
+   * 'lastUsed' - on first drawer run plugin options.defaultActivePlugin.name, on consecutive - last used tool
+   *
+   * @param {Object} options.canvasProperties
+   * Specifies fabricjs options that will be passed directly to fabricjs
+   * canvas instance on creation.
+   *
+   * @param {String} options.canvasProperties.selectionColor
+   * Specifies color of selection rectangle.
+   *
+   *
+   * @param {number[]} options.canvasProperties.selectionDashArray
+   * What it allows us to do is make selection lines dashed.
+   * <br><br>
+   *
+   * The way to define dash pattern is by specifying intervals via an array.
+   * <br><br>
+   * So to create a pattern where there's one long dash followed by one short
+   * dash, we could use something like <code>[10, 5]</code>
+   * as "selectionDashArray".
+   * <br>
+   *
+   * This will draw a line that's 10px long, then skip 5px, draw 10px line
+   * again, and so on.<br>
+   * If we were to use <code>[2, 4, 6]</code> array, the pattern would be
+   * created by drawing 2px line, then skipping 4px, then drawing 6px line,
+   * then skipping 2px, then drawing 4px line, then skipping 6px, and so on.
+   * You get the point.
+   *
+   *
+   * @param {number} options.canvasProperties.selectionLineWidth
+   * Specifies selection line width in pixels.
+   *
+   *
+   * @param {String} options.canvasProperties.selectionBorderColor
+   * Specifies selection line color.
+   *
+   *
+   * @param {Object} options.objectControls
+   * Specifies the appearance of selected object controls.
+   *
+   *
+   * @param {String} options.objectControls.borderColor
+   * Specifies selected object border color.
+   *
+   *
+   * @param {float} options.objectControls.borderOpacityWhenMoving
+   * Specifies border opacity when object is selected and in moving process.
+   *
+   *
+   * @param {String} options.objectControls.cornerColor
+   * Specified color of control corners for resizing/rotating.
+   *
+   *
+   * @param {number} options.objectControls.cornerSize
+   * Specifies size of corners for resizing/rotating.
+   *
+   *
+   * @param {boolean} options.objectControls.hasBorders
+   * Toggles visibility of selected object border.
+   *
+   * @param {Object} options.objectControlsTouch
+   * The same as <code>objectControls</code> but will be used
+   * when touch device is detected.
+   *
+   * @param {Function} options.detectTouch
+   * A custom function that will be used by drawer to determine whether it is
+   * running on touch device or not.
+   * <br><br>
+   *
+   * This function must return <code>true</code> or <code>false</code>.
+   * <br><br>
+   *
+   * <code>true</code> means that touch device is detected and drawer should
+   * adjust its toolbar sized, add touch events etc.
+   * <br><br>
+   *
+   * Note that if this function is not specified, drawer will use its own
+   * detection mechanism.
+   * <br><br>
+   *
+   * To disable any detection simply set this parameter to such function:
+   * <code><pre>function() { return false; }</pre></code>
+   *
+   *
+   * @param {Object} options.contentConfig
+   * Specifies data-management configuration and controls where canvas element
+   * will store its information.
+   *
+   *
+   * @param {number} options.contentConfig.saveAfterInactiveSec
+   * Specifies number of seconds to wait after user interaction.
+   * If nothing happens in that time - canvas will be saved.
+   * Any interaction resets the timer.
+   *
+   * @param {boolean} options.contentConfig.saveInHtml
+   * Controls whether a drawer will save its content to underlying
+   * image element.
+   * <br><br>
+   *
+   * If <code>true</code>, canvas objects data will be serialized to JSON and
+   * appended to image's <code>data-canvas-serialized</code> attribute.
+   * <br><br>
+   *
+   * Note that JSON could be huge on canvases with a lot of objects and
+   * freedrawings.
+   *
+   *
+   * @param {String|jQuery} options.contentConfig.imagesContainer
+   * Specifies external data container for canvas images data.
+   * <br><br>
+   *
+   * Canvas will serialize itself into base64 encoded png image and
+   * store it as json-encoded text to that container.
+   * <br><br>
+   *
+   * This could be used for storing rendered images separately from content.
+   * <br><br>
+   *
+   * JSON example:
+   * <code><pre>
+   * {
+   *    'canvas_id': 'base64/png .....'
+   * }
+   * </pre></code>
+   *
+   *
+   * @param {String|jQuery} options.contentConfig.canvasDataContainer
+   * Specifies external data container for canvas data.
+   * <br><br>
+   *
+   * Canvas will serialize itself into json object containing all the vector
+   * objects on canvas and its parameters like angle, color etc.
+   * <br><br>
+   *
+   * This could be used for storing canvas vector data separately from content.
+   * <br><br>
+   *
+   * JSON example:
+   * <code><pre>
+   * {
+   *    'canvas_id': {
+   *        'objects': []
+   *    }
+   * }
+   * </pre></code>
+   *
+   * @param {Function} options.contentConfig.loadCanvasData
+   * Specifies a function that will be called when editable canvas needs to
+   * load its fabricjs data.
+   * <br><br>
+   * <code>function(canvasId)</code>
+   *
+   * @param {Function} options.contentConfig.saveCanvasData
+   * Specifies a function that will be called when editable canvas needs to
+   * store its fabricjs data.
+   * <br><br>
+   * <code>function(canvasId, canvasData)</code>
+   *
+   * @param {Function} options.contentConfig.loadImageData
+   * Specifies a function that will be called when editable canvas needs to
+   * load base64/png image data data.
+   * <br><br>
+   * <code>function(canvasId)</code>
+   *
+   * @param {Function} options.contentConfig.saveImageData
+   * Specifies a function that will be called when editable canvas needs to
+   * save base64/png image data data.
+   * <br><br>
+   * <code>function(canvasId, imageData)</code>
+   *
+   * @param {string} options.basePath
