+/**
+ * @class Ext.draw.Sprite
+ * @extends Object
+ *
+ * A Sprite is an object rendered in a Drawing surface. There are different options and types of sprites.
+ * The configuration of a Sprite is an object with the following properties:
+ *
+ * - **type** - (String) The type of the sprite. Possible options are 'circle', 'path', 'rect', 'text', 'square'.
+ * - **width** - (Number) Used in rectangle sprites, the width of the rectangle.
+ * - **height** - (Number) Used in rectangle sprites, the height of the rectangle.
+ * - **size** - (Number) Used in square sprites, the dimension of the square.
+ * - **radius** - (Number) Used in circle sprites, the radius of the circle.
+ * - **x** - (Number) The position along the x-axis.
+ * - **y** - (Number) The position along the y-axis.
+ * - **path** - (Array) Used in path sprites, the path of the sprite written in SVG-like path syntax.
+ * - **opacity** - (Number) The opacity of the sprite.
+ * - **fill** - (String) The fill color.
+ * - **stroke** - (String) The stroke color.
+ * - **stroke-width** - (Number) The width of the stroke.
+ * - **font** - (String) Used with text type sprites. The full font description. Uses the same syntax as the CSS `font` parameter.
+ * - **text** - (String) Used with text type sprites. The text itself.
+ *
+ * Additionally there are three transform objects that can be set with `setAttributes` which are `translate`, `rotate` and
+ * `scale`.
+ *
+ * For translate, the configuration object contains x and y attributes that indicate where to
+ * translate the object. For example:
+ *
+ * sprite.setAttributes({
+ * translate: {
+ * x: 10,
+ * y: 10
+ * }
+ * }, true);
+ *
+ * For rotation, the configuration object contains x and y attributes for the center of the rotation (which are optional),
+ * and a `degrees` attribute that specifies the rotation in degrees. For example:
+ *
+ * sprite.setAttributes({
+ * rotate: {
+ * degrees: 90
+ * }
+ * }, true);
+ *
+ * For scaling, the configuration object contains x and y attributes for the x-axis and y-axis scaling. For example:
+ *
+ * sprite.setAttributes({
+ * scale: {
+ * x: 10,
+ * y: 3
+ * }
+ * }, true);
+ *
+ * Sprites can be created with a reference to a {@link Ext.draw.Surface}
+ *
+ * var drawComponent = Ext.create('Ext.draw.Component', options here...);
+ *
+ * var sprite = Ext.create('Ext.draw.Sprite', {
+ * type: 'circle',
+ * fill: '#ff0',
+ * surface: drawComponent.surface,
+ * radius: 5
+ * });
+ *
+ * Sprites can also be added to the surface as a configuration object:
+ *
+ * var sprite = drawComponent.surface.add({
+ * type: 'circle',
+ * fill: '#ff0',
+ * radius: 5
+ * });
+ *
+ * In order to properly apply properties and render the sprite we have to
+ * `show` the sprite setting the option `redraw` to `true`:
+ *
+ * sprite.show(true);
+ *
+ * The constructor configuration object of the Sprite can also be used and passed into the {@link Ext.draw.Surface}
+ * add method to append a new sprite to the canvas. For example:
+ *
+ * drawComponent.surface.add({
+ * type: 'circle',
+ * fill: '#ffc',
+ * radius: 100,
+ * x: 100,
+ * y: 100
+ * });
