The Avg and FPS line used traced self-time, which reads too high. Measure the time between overlay frames instead. Draw the graph with PlotLineG so the history deque needs no per-frame copy. Co-Authored-By: Claude Sonnet 5.5 <[email protected]>

* Drains the frame profiler (see frame_profile_process_frame()), folds the wall-clock time since
|
|
* the previous overlay frame into the rolling history behind the graph/avg/median, and contributes the overlay window
|
|
* -- avg/median frametime, a scrolling frametime graph, a stacked frame-budget bar of the top
|
|
* traced categories by self-time, and the -gr_debug graphics stats -- to this frame's ImGui pass,
|
|
* opening one via gr_imgui_begin_frame() if no other consumer already has.
|
|
*
|
|
* No-op when frame profiling is disabled. Being the single per-frame driver is what keeps the
|
|
* profiler's event buffer bounded in every game state, so it must stay on the common flip path
|
|
* rather than being called per game state.
