This is called before a event.

only passed RunType::Idle to Context::run.

fn post_processing(&mut self)

This is called after a event.

only passed RunType::Idle to Context::run.

fn draw(&mut self, _: &Window)

This is called when the window needs redrawing.

fn activated(&mut self, _: &Window)

This is called when the window has been activated.

fn inactivated(&mut self, _: &Window)
