+ *
+ * The Draw Component is a surface in which sprites can be rendered. The Draw Component
+ * manages and holds a `Surface` instance: an interface that has
+ * an SVG or VML implementation depending on the browser capabilities and where
+ * Sprites can be appended.
+ *
+ * One way to create a draw component is:
+ *
+ * @example
+ * var drawComponent = Ext.create('Ext.draw.Component', {
+ * viewBox: false,
+ * items: [{
+ * type: 'circle',
+ * fill: '#79BB3F',
+ * radius: 100,
+ * x: 100,
+ * y: 100
+ * }]
+ * });
+ *
+ * Ext.create('Ext.Window', {
+ * width: 215,
+ * height: 235,
+ * layout: 'fit',
+ * items: [drawComponent]
+ * }).show();
+ *
+ * In this case we created a draw component and added a sprite to it.
+ * The *type* of the sprite is *circle* so if you run this code you'll see a yellow-ish
+ * circle in a Window. When setting `viewBox` to `false` we are responsible for setting the object's position and
+ * dimensions accordingly.
+ *
+ * You can also add sprites by using the surface's add method:
+ *
+ * drawComponent.surface.add({
+ * type: 'circle',
+ * fill: '#79BB3F',
+ * radius: 100,
+ * x: 100,
+ * y: 100
+ * });
+ *
+ * For more information on Sprites, the core elements added to a draw component's surface,
+ * refer to the Ext.draw.Sprite documentation.
