The renderer of an Image.

Your renderer will need to implement this trait before being able to use an Image in your user interface.

Required methods

`fn node( &self, style: Style, image: &I, width: Option<u16>, height: Option<u16>, source: Option<Rectangle<u16>> ) -> Node`

Creates a Node with the given Style for the provided Image and its size.

You should probably keep the original aspect ratio, if possible.

`fn draw( &mut self, image: &I, bounds: Rectangle<f32>, source: Option<Rectangle<u16>> )`

Draws an Image.

It receives:

the bounds of the Image
the handle of the loaded Image
the portion of the image to draw. If not specified, the entire image should be drawn.
