Trait implemented by things that can draw brush strokes

Required Methods

fn brush_points_for_raw_points(
    &self,
    raw_points: &[RawPoint]
) -> Vec<BrushPoint>

Returns the brush points for rendering given a particular set of raw points

fn prepare_to_render<'a>(
    &'a self,
    properties: &'a BrushProperties
) -> Box<Iterator<Item = Draw> + 'a>

One or more brush strokes of this type are about to be rendered. This brush should set up the graphics context appropriately.

fn render_brush<'a>(
    &'a self,
    properties: &'a BrushProperties,
    points: &'a Vec<BrushPoint>
) -> Box<Iterator<Item = Draw> + 'a>

Renders a brush stroke to the specified graphics context

fn to_definition(&self) -> (BrushDefinition, BrushDrawingStyle)

Retrieves the definition for this brush
