// ***********************************************************************
//
//
//
//
// 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
//  MICROPROFILE_LABEL
//  MICROPROFILE_LABELF
//
//	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 MicroProfileGpuInsertTimer(void* pContext);
// 		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 1
// 			call MicroProfileGpuInitGL() on startup
//		D3D11:
// 			in .c file where MICROPROFILE_IMPL is defined:
//   		#define MICROPROFILE_GPU_TIMERS_D3D11 1
// 			call MicroProfileGpuInitD3D11(Device) on startup
//		D3D12:
// 			in .c file where MICROPROFILE_IMPL is defined:
//   		#define MICROPROFILE_GPU_TIMERS_D3D12 1
// 			call MicroProfileGpuInitD3D12(Device, CommandQueue) on startup
//			single-threaded: call MicroProfileGpuSetContext(CommandList) every frame before issuing GPU markers
//			multi-threaded:
//				#define MICROPROFILE_GPU_TIMERS_MULTITHREADED 1
//				on recording thread before using command list, call MicroProfileGpuBegin(CommandList)
//				on recording thread after you're done with command list, call work = MicroProfileGpuEnd()
//				when replaying, call MicroProfileGpuSubmit(work) in the same order as ExecuteCommandLists
//		Vulkan:
// 			in .c file where MICROPROFILE_IMPL is defined:
//   		#define MICROPROFILE_GPU_TIMERS_VK 1
// 			call MicroProfileGpuInitVK(Device, PhysicalDevice, Queue) on startup
// 			the rest is the same as for D3D12
//
// Limitations:
//  GPU timestamps can only be inserted from one thread.
