 /**
  * The paint describes how color and coverage are computed at each pixel by GrContext draw
  * functions and the how color is blended with the destination pixel.
  *
  * The paint allows installation of custom color and coverage stages. New types of stages are
  * created by subclassing GrProcessor.
  *
  * The primitive color computation starts with the color specified by setColor(). This color is the
  * input to the first color stage. Each color stage feeds its output to the next color stage.
