/**
  \class nvvk::AppWindowProfilerVK

  nvvk::AppWindowProfilerVK derives from nvh::AppWindowProfiler
  and overrides the context and swapbuffer functions.
  The nvh class itself provides several utilities and 
  command line options to run automated benchmarks etc.
  
  To influence the vulkan instance/device creation modify 
  `m_contextInfo` prior running AppWindowProfiler::run,
  which triggers instance, device, window, swapchain creation etc.

  The class comes with a nvvk::ProfilerVK instance that references the 
  AppWindowProfiler::m_profiler's data.
