Defined at line 25 of file ../../src/ui/scenic/lib/flatland/renderer/null_renderer.h

A renderer implementation used for validation. It does everything a standard

renderer implementation does except for actually rendering.

void Render (const allocation::ImageMetadata & render_target, const std::vector<EngineLayer> & layers, const std::vector<EngineLayerImage> & images, const RenderArgs & render_args)

Check that the buffer collections for each of the images passed in have been validated.

DCHECK if they have not.
