Struct flo_canvas::SpriteId

pub struct SpriteId(pub u64);

Identifier of a canvas 'sprite'

A 'sprite' is just a placeholder for a set of pre-rendered actions (it's useful for things like images or drawings that are expected to repeat). Sprites survive layer and canvas clears so they can be re-used repeatedly. The drawing layer may cache these actions in order to render the sprite quickly.

Sprites are also faster to draw when rendering to a remote surface as they only need to be sent across once before they can be re-rendered as often as necessary.
