FrameProfileSummary

Kind	typedef
Package	debug
Full name	debug.FrameProfileSummary
Source	source/debug/FrameProfiler.hx

Aggregated statistical summary across the profiling session and ring buffer.

Percentile & Low-FPS Semantics:

• Percentiles (p50, p95, p99, p999) use Hyndman-Fan Type 7 linear interpolation (pos = q * (N - 1)) over the ring buffer (up to 2,048 frames).
• onePercentLowFps = 1000.0 / p99FrameTimeMs (reciprocal of P99 frametime).
• pointOnePercentLowFps = 1000.0 / p999FrameTimeMs (reciprocal of P99.9 frametime).
• slowest1PctAvgFps and slowest01PctAvgFps = harmonic mean FPS of the slowest ceil(0.01 * N) and ceil(0.001 * N) buffered frames.
• cpuTimeAvailable, rssAvailable, heapStatsAvailable explicitly indicate whether the underlying platform/runtime metrics are available.
