Detailed Description

Per-renderer timing state for the on-screen FPS overlay.

Per-renderer timing state for the on-screen FPS overlay

Tracks visibility, the frame currently being measured, write completion and failure state, plus monotonic timestamps used to calculate the rolling FPS value and periodically report render timing. The timestamp ring and this state belong to one renderer thread and are hidden behind fps_counter_t.
