// after cc::PixelTest::SetUp() has run, which creates the renderer. Then it
// can be used to create and give ink metadata and points to |renderer_|'s
// delegated ink point renderer. The metadata and points are stored so that the
// information can be used for future points and metadata (i.e. when a point
// needs to match the metadata for the first point of a trail) or when
// determining the damage rect to apply to a render pass.
