// This class stores the information required to draw a single point of a
// delegated ink trail. When the WebAPI |updateInkTrailStartPoint| is called,
// the renderer requests that the browser begin sending these to viz. Viz
// will collect them, and then during |DrawAndSwap| will use the
// DelegatedInkPoints that have arrived from the browser along with the
// DelegatedInkMetadata that the renderer sent to draw a delegated ink trail on
// the screen, connected to the end of the already rendered ink stroke.
