FrameData NewFrame (vk::ImageLayout framebuffer_layout)

Defined at line 59 of file ../../src/ui/lib/escher/test/common/readback_test.cc

std::vector<uint8_t> ReadbackFromColorAttachment (const FramePtr & frame, vk::ImageLayout current_image_layout, vk::ImageLayout final_image_layout)

Submits the frame's commands via SubmitPartialFrame(), after first adding

commands to readback the output image. Waits until the Vulkan device is

idle, then memcpys the image bytes into the returned result.
