// High precision, low overhead time measurements. Returns exact call counts and
// total elapsed time for user-defined 'zones' (code regions, i.e. C++ scopes).
//
// To use the profiler you must set the JPEGXL_ENABLE_PROFILER CMake flag, which
// defines PROFILER_ENABLED and links against the libjxl_profiler library.
// If zero, this file has no effect and no measurements will be recorded.
