  profiler::time_section("Main");

  profiler::time_subsection("Sleep 1.5 seconds");
  sleep1s();

  profiler::section_start("Sleep 0.25s");
  	std::this_thread::sleep_for(0.25s);
  profiler::section_end();

  profiler::time_subsection("Sleep 0.25s again", 2);
  std::this_thread::sleep_for(0.25s);

  profiler::time_subsection("Sleep 0.5s");
  std::this_thread::sleep_for(0.5s);

  profiler::print_summary();
}

Save canvas in simple image format PPM.
