This file delivers three related timing utilities:

1. Timer — manual high precision stopwatch (microsecond resolution) for ad hoc measurements.
2. ScopedTimer — RAII wrapper that records elapsed time on destruction, storing results in a global list for later inspection or logging.
3. Time — simple static access to the current GLFW time (in seconds) for driving frame based deltas.

Usage patterns:

• Use Timer when you need start/stop control: cpp Timer t; // ... code to measure ... float ms = t.ElapsedMillis();
• Use ScopedTimer to automatically record durations of a scope: cpp { ScopedTimer timer("MyTask", 5.0f (ms threshold)); // ... work ... } // on destruction, logs if greater than threshold and stores in TimerData list
• Use Time::GetTime() each frame to compute delta and drive a Timestep.

Note

• Timer measures in microseconds internally, but returns seconds or milliseconds as floats.
• ScopedTimer collects every named timing in a static vector—inspect via ScopedTimer::GetTimers().
• Time::GetTime() wraps glfwGetTime(), so it shares GLFW's epoch (time since initialization).
