// SolidColorDrawQuad which is white, a TextureDrawQuad and finally an
// AggregatedRenderPassDrawQuad would look like:
//
// EXPECT_THAT(render_pass->quad_list,
// testing::ElementsAre(IsSolidColorQuad(SK_ColorWHITE),
// IsTextureQuad(),
// IsAggregatedRenderPassQuad()));
//
// Add additional matcher generation functions to this file for DrawQuad types
// and attributes that aren't implemented yet.
