// ***********************************************************************
//
//
//
//
// Howto:
// Call these functions from your code:
//  MicroProfileOnThreadCreate
//  MicroProfileMouseButton
//  MicroProfileMousePosition
//  MicroProfileModKey
//  MicroProfileFlip                <-- Call this once per frame
//  MicroProfileDraw                <-- Call this once per frame
//  MicroProfileToggleDisplayMode   <-- Bind to a key to toggle profiling
//  MicroProfileTogglePause         <-- Bind to a key to toggle pause
//
// Use these macros in your code in blocks you want to time:
//
//  MICROPROFILE_DECLARE
//  MICROPROFILE_DEFINE
//  MICROPROFILE_DECLARE_GPU
//  MICROPROFILE_DEFINE_GPU
//  MICROPROFILE_SCOPE
//  MICROPROFILE_SCOPEI
//  MICROPROFILE_SCOPEGPU
//  MICROPROFILE_SCOPEGPUI
//  MICROPROFILE_META
//
//
//  Usage:
//
//  {
//      MICROPROFILE_SCOPEI("GroupName", "TimerName", nColorRgb):
//      ..Code to be timed..
//  }
//
//  MICROPROFILE_DECLARE / MICROPROFILE_DEFINE allows defining groups in a shared place, to ensure sorting of the timers
//
//  (in global scope)
//  MICROPROFILE_DEFINE(g_ProfileFisk, "Fisk", "Skalle", nSomeColorRgb);
//
//  (in some other file)
//  MICROPROFILE_DECLARE(g_ProfileFisk);
//
//  void foo(){
//      MICROPROFILE_SCOPE(g_ProfileFisk);
//  }
//
//  Once code is instrumented the gui is activeted by calling MicroProfileToggleDisplayMode or by clicking in the upper left corner of
//  the screen
//
// The following functions must be implemented before the profiler is usable
//  debug render:
//      void MicroProfileDrawText(int nX, int nY, uint32_t nColor, const char* pText, uint32_t nNumCharacters);
//      void MicroProfileDrawBox(int nX, int nY, int nX1, int nY1, uint32_t nColor, MicroProfileBoxType = MicroProfileBoxTypeFlat);
//      void MicroProfileDrawLine2D(uint32_t nVertices, float* pVertices, uint32_t nColor);
//  Gpu time stamps: (See below for d3d/opengl helper)
//      uint32_t MicroProfileGpuInsertTimeStamp();
//      uint64_t MicroProfileGpuGetTimeStamp(uint32_t nKey);
//      uint64_t MicroProfileTicksPerSecondGpu();
//  threading:
//      const char* MicroProfileGetThreadName(); Threadnames in detailed view
//
// Default implementations of Gpu timestamp functions:
//      Opengl:
//          in .c file where MICROPROFILE_IMPL is defined:
//          #define MICROPROFILE_GPU_TIMERS_GL
//          call MicroProfileGpuInitGL() on startup
//      D3D11:
//          in .c file where MICROPROFILE_IMPL is defined:
//          #define MICROPROFILE_GPU_TIMERS_D3D11
//          call MICROPROFILE_GPU_TIMERS_D3D11(). Pass Device & ImmediateContext
//
// Limitations:
//  GPU timestamps can only be inserted from one thread.
