Fabian WoltermannandClaude Opus 5.5 8ef44a411d ImGui frame profiler overlay, and Vulkan per-draw descriptor set churn fix (#7694) 
* chore: vendor ImPlot library

Adds ImPlot as a build dependency, to be used for the upcoming ImGui
frame profiler overlay's frametime graph and pie chart.

* feat: add ImGui frame profiler overlay

Replaces the old text-dump frame profile display (-profile_frame_time)
with a runtime-toggleable ImGui/ImPlot overlay showing average/median
frametime, a scrolling frametime graph, and a pie chart of the top
contributors to frame time. Toggled via a new "Frame Profiler Overlay"
option, which also seeds from -profile_frame_time for backward
compatibility and now drives frame profiling collection at runtime
instead of only at startup.

* Add graphics and Vulkan debug stats to ImGui profiler overlay

- Integrated per-backend diagnostic counters into the ImGui frame profiler overlay, triggered by `-gr_debug`.
- Consolidated and cleaned up Vulkan rendering state and descriptor management for compatibility with ImGui's Vulkan pipeline.
- Enabled uniform buffer and draw statistics reporting for enhanced performance insights during debugging.

* Update ImPlot to v1.1 WIP and improve internal consistency

- Adjust copyright notices for extended license coverage (2025-2026).
- Modernize constants with `constexpr` replacements, improving type safety and clarity.
- Enforce `nullptr` usage over `NULL` throughout, aligning with modern C++ practices.
- Add various enhancements to ImPlot legends, markers, and axes behavior.
- Introduce additional helper methods for time handling and timestamp calculations.
- Address UI and typo improvements in comments and documentation, refining accuracy.

* Refactor frame profiler to use per-category self-time accumulation

- Introduced `accumulate_self_times` for single-pass exclusive time computation, improving performance and accuracy.
- Updated `FrameProfiler` and overlay snapshot logic to leverage `Category`'s stable `getId` and `getCount`.
- Replaced pie chart with a stacked bar for frame budget visualization, optimizing rendering cost.
- Cached `get_tid` and `get_pid` with thread-local storage to minimize syscall overhead.
- Added support for unit testing frame profiling functionality and included new test cases.
- Improved code comments and clarified documentation.

* Use dynamic uniform buffers to stop per-draw descriptor set churn in Vulkan

The Material and PerDraw descriptor sets were reallocated and fully rewritten on
essentially every draw call. model_draw_list::render_buffer rebinds ModelData with
a fresh uniform buffer offset for each queued draw, and that offset was part of the
Material set's memoization key, so the cache in VulkanDrawManager::applyMaterial
missed every time - taking a frame-pool allocation, a full template write, the
16-entry material texture resolution and a vkUpdateDescriptorSets with it.
GenericData/Matrices did the same to the PerDraw set. renderShadowDraw was worse
still: all three sets allocated and rewritten per shadow draw, with no memoization
at all.

A large asteroid field (Solaris m21) measured 2566 descriptor sets and 19107
descriptor writes per frame at 1606 model draws, and grew an extra descriptor pool
chunk every frame.

Declare the bindings whose offset moves per draw - MaterialBinding::ModelData,
MaterialBinding::ShadowMapData, PerDrawBinding::GenericData and
PerDrawBinding::Matrices - as eUniformBufferDynamic. DescriptorWriter::setBuffer
now splits a dynamic binding's offset out of the descriptor, writing
{buffer, 0, range} and stashing the offset for vkCmdBindDescriptorSets'
pDynamicOffsets, so an offset-only change leaves the set's contents identical and
the memoization caches start hitting. Shader sources are unchanged.

VulkanStateTracker::bindDescriptorSet now compares the dynamic offsets as well as
the set handle. This is required, not an optimization: the common case is now the
same set rebound with a new offset, and the old handle-only redundancy check would
have skipped that bind and fed every draw the previous draw's uniforms.

renderShadowDraw memoizes its three sets the way applyMaterial does. It does not
invalidate applyMaterial's caches - those record what a set contains, the shadow
pass allocates its own sets rather than overwriting theirs, and it binds through
the state tracker, so the next material cache hit still rebinds correctly.

Also switch allocateFrameSet to the non-allocating allocateDescriptorSets overload;
the vector-returning one heap-allocated once per set, thousands of times a frame.
MAX_SETS_PER_POOL stays at 1024 - the per-frame pool growth it used to log was a
symptom of the churn, and one chunk now covers the scene outright.

Measured on that mission in a Debug build, A/B on the same tree with and without
this change:

  descriptor sets/frame  @ ~1370 draws  2566   -> 250-345
  descriptor writes/frame                19107 -> ~1700-2300
  median frametime                       92.9/83.6 ms -> 72.0/66.5 ms
  Render Buffer (profiler overlay)       24.68 ms (30.8%) -> 12.73 ms (18.4%)
  Build Shadow Map                       5.44 ms -> off the top-5 entirely

Release builds already inlined most of this away and are unchanged, as expected.
Verified with the validation layers (sync validation enabled): no new VUIDs versus
the same build without the change.

* Refactor Vulkan descriptor set binding to reduce dynamic offset churn

- Consolidated dynamic descriptor offset logic into `DescriptorWriter::bindSets`, replacing repetitive `vkCmdBindDescriptorSets` patterns across Vulkan modules.
- Eliminated redundant descriptor binding operations for Material and PerDraw sets by centralizing logic in `bindSets`.
- Simplified descriptors by directly splitting offset changes from descriptor contents, avoiding unnecessary updates.
- Updated comments and documentation to align with the new approach while maintaining reference consistency.
- Applied optimizations across Vulkan modules (`VulkanPostProcessing`, `VulkanDescriptorManager`, etc.) to reduce per-draw overhead and improve readability.

* Enable primitive restart for supported topologies in Vulkan pipeline

- Added `topologySupportsPrimitiveRestart` to determine restart eligibility for each topology.
- Updated `primitiveRestartEnable` to be conditionally set based on topology, addressing compatibility issues with Metal/MoltenVK.
- Prevented crash scenarios on macOS by ensuring pipelines are valid for strip/fan topologies requiring primitive restart.

* Enable VK_KHR_portability_subset for compatibility

* Replace exception with sentinel for non-dynamic Vulkan descriptor bindings

- Introduced `DYNAMIC_SLOT_INVALID` sentinel to replace the throw in `dynamic_offset_slot` for MSVC compatibility.
- Added `static_assert` checks to validate binding constants, ensuring compile-time validation for dynamic offsets.
- Updated comments to clarify design rationale and avoid potential misuse.

* Add memory statistics and tracking to profiler overlay

* fix ci issues

* Add OpenGL memory statistics to the profiler overlay

The memory panel showed no texture bytes and no geometry bytes under
OpenGL. Only the depth renderbuffers went into the render target group.
All three groups now give a value.

Textures: GL_texture_bytes_used holds the bytes of every live texture
cache slot. opengl_texture_release_bytes() removes the bytes of a slot at
each site that drops its texture data. The bitmap render targets record
the bytes of their color texture.

Geometry: the unused GL_vertex_data_in global becomes
GL_geometry_bytes_used, which counts only vertex and index buffers. This
matches the geometry group of the Vulkan backend.
gr_opengl_delete_buffer() sets the size of the buffer to 0, because
opengl_destroy_all_buffers() calls it a second time for a buffer that the
game already deleted.

Render targets: three new functions add the scene textures, the
post-processing textures, and the shadow map to the group. They sum the
bytes at the moment of the call from the textures that exist, thus they
need no bookkeeping at the create and delete sites.

* Fix profiler overlay crash on a category that is not a static

The category registry kept a Category pointer for each id. The comment said that all categories
are global statics, but that is not correct. The Lua API tracing_category constructs a Category
and copies it into a script-owned object. The registry then kept a pointer to the dead temporary.
build_overlay_snapshot called getName() on that pointer, made an SCP_string from the garbage
char*, and the process stopped with SIGABRT.

The registry now keeps the name by value and never keeps a Category pointer. getById() becomes
getNameById(), which is all that build_overlay_snapshot needs. A copy of a Category keeps the id
of the original, which stays correct because the id only selects a name.

Add two tests: one shows that the name stays available after the Category object is dead, and one
drives the full path that failed, from processEvent to the overlay snapshot.

Co-Authored-By: Claude Opus 5 <[email protected]>

* Replace category pointers with IDs to prevent use-after-free

- Updated `trace_event` to store `category_id` instead of a pointer to prevent dangling references to category objects that may already be destroyed.
- Modified all references to category names to use `Category::getNameById()` instead of dereferencing pointers.
- Expanded memory statistics in the profiler overlay with new sound, Lua, and OS-level memory usage tracking.
- Added new tests to verify proper use of category IDs in frame profiling and event tracing.
- Improved memory safety and stability across tracing, profiling, and overlay systems.

* Refactor profiler overlay to use snapshot-based frame timing

* Address review feedback on the profiler overlay

Skip complete::end for a scope that did not start. This fixes a crash
when Lua turns the overlay on while a scope is open. Track the GPU begin
event so that turning the overlay off mid-scope still closes it.

Use XSTR 1936 and 1937 for the overlay option. Master now uses 1932
and 1933.

Remove the default value of dynamicOffsets in bindDescriptorSet. Use the
PerDraw binding constants in the PerDraw key.

* Use wall-clock frame time and read the history without a copy

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]>

* Address second round of review feedback on the profiler overlay

- Make the category registry thread-safe and give categories with the
  same name one id, so the registry does not grow without limit.
- Add tests that toggle the profiler inside an open trace scope.
- Correct the next free XSTR id note to 1938.
- Use the existing Windows include block for psapi.h in osapi.cpp.
- Use list_range in ship_get_num_ships() and shorten some comments.

Co-Authored-By: Claude Opus 5.5 <[email protected]>

* Return size_t from Category::getCount() and tidy the registry code

- Use structured bindings and std::scoped_lock in the category registry.
- Return size_t from getCount() and update its callers and tests.

Co-Authored-By: Claude Opus 5.5 <[email protected]>

* Address third round of review feedback on the profiler overlay

- Move the overlay option strings to XSTR 1940 and 1941. The touch
  overlay on master uses 1936 to 1939.
- Give FrameProfiler the main thread ID when it is made. Before, it
  used the thread of the first event, which was a race.
- Let mouse motion go to the game while the pointer is over the
  overlay, so that mouse flight does not stop there.
- Find the dynamic bindings of the PerDraw key with
  dynamic_offset_slot(), as the other call sites do.
- Make disable_inside_open_scope count the GPU timestamp queries, so
  that it fails if end() does not close the GPU event.
- Make the copy test copy the category, not bind a reference.

API BREAKING CHANGES
====================
Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.
Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.
When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all implot files.
You can read releases logs https://github.com/epezent/implot/releases for more details.
- 2026/02/12 (1.0) - ImPlotSpec replaces the SetNextXXX style functions. The guide below shows show to migrate from SetNextXXX to ImPlotSpec.
- `SetNextLineStyle` has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextLineStyle(line_color, line_weight);
ImPlot::PlotLine("Line", xs, ys, count);
// After
ImPlotSpec spec;
spec.LineColor = line_color;
spec.LineWeight = line_weight;
ImPlot::PlotLine("Line", xs, ys, count, spec);
```
- `SetNextFillStyle` has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextFillStyle(fill_color, fill_alpha);
ImPlot::PlotLine("Shaded", xs, ys, count, ImPlotLineFlags_Shaded);
// After
ImPlotSpec spec;
spec.FillColor = fill_color;
spec.FillAlpha = fill_alpha;
spec.Flags = ImPlotLineFlags_Shaded;
ImPlot::PlotTLine("Shaded", xs, ys, count, spec);
```
- SetNextMarkerStyle has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextMarkerStyle(marker, marker_size, fill_color, line_weight, marker_outline_color);
ImPlot::PlotScatter("Scatter", xs, ys, count);
// After
ImPlotSpec spec;
spec.LineWeight = line_weight;
spec.Marker = marker;
spec.MarkerSize = marker_size;
spec.MarkerLineColor = marker_outline_color;
spec.MarkerFillColor = fill_color;
ImPlot::PlotScatter("Scatter", xs, ys, count, spec);
```
- SetNextErrorBarStyle has been removed, styling should be set via ImPlotSpec.
```
// Before
ImPlot::SetNextErrorBarStyle(color, size, weight);
ImPlot::PlotErrorBars("ErrorBar", xs, ys, err, count);
// After
ImPlotSpec spec;
spec.LineColor = color;
spec.Size = size;
spec.LineWeight = weight;
ImPlot::PlotErrorBars("ErrorBar", xs, ys, err, count, spec);
```
- Flags, Offset and Stride should also be set via ImPlotSpec now.
- 2023/10/02 (1.0) - ImPlotSpec was made the default and _only_ way of styling plot items. Therefore the following features were removed:
- ImPlotCol_Line, ImPlotCol_Fill, ImPlotCol_MarkerOutline, ImPlotCol_MarkerFill, ImPlotCol_ErrorBar have been removed and thus are no longer supported by PushStyleColor.
You can use a common ImPlotSpec instance across multiple PlotX calls to emulate PushStyleColor behavior.
- ImPlotStyleVar_LineWeight, ImPlotStyleVar_Marker, ImPlotStyleVar_MarkerSize, ImPlotStyleVar_MarkerWeight, ImPlotStyleVar_FillAlpha, ImPlotStyleVar_ErrorBarSize, and ImPlotStyleVar_ErrorBarWeight
have been removed and thus are no longer supported by PushStyleVar. You can use a common ImPlotSpec instance across multiple PlotX calls to emulate PushStyleVar behavior.
- ImPlotStyle/ImPlotStyleVar_ DigitalBitGap was renamed to DigitalSpacing; DigitalBitHeight was removed (use ImPlotSpec::Size); DigitalPadding was added for padding from bottom.
- PlotX offset, stride, and flags parameters are now incorporated into ImPlotSpec; specify these variables in the ImPlotSpec passed to PlotX.
- 2023/08/20 (0.17) - ImPlotFlags_NoChild was removed as child windows are no longer needed to capture scroll. You can safely remove this flag if you were using it.
- 2023/06/26 (0.15) - Various build fixes related to updates in Dear ImGui internals.
- 2022/11/25 (0.15) - Make PlotText honor ImPlotItemFlags_NoFit.
- 2022/06/19 (0.14) - The signature of ColormapScale has changed to accommodate a new ImPlotColormapScaleFlags parameter
- 2022/06/17 (0.14) - **IMPORTANT** All PlotX functions now take an ImPlotX_Flags `flags` parameter. Where applicable, it is located before the existing `offset` and `stride` parameters.
If you were providing offset and stride values, you will need to update your function call to include a `flags` value. If you fail to do this, you will likely see
unexpected results or crashes without a compiler warning since these three are all default args. We apologize for the inconvenience, but this was a necessary evil.
- PlotBarsH has been removed; use PlotBars + ImPlotBarsFlags_Horizontal instead
- PlotErrorBarsH has been removed; use PlotErrorBars + ImPlotErrorBarsFlags_Horizontal
- PlotHistogram/PlotHistogram2D signatures changed; `cumulative`, `density`, and `outliers` options now specified via ImPlotHistogramFlags
- PlotPieChart signature changed; `normalize` option now specified via ImPlotPieChartFlags
- PlotText signature changes; `vertical` option now specified via `ImPlotTextFlags_Vertical`
- `PlotVLines` and `PlotHLines` replaced with `PlotInfLines` (+ ImPlotInfLinesFlags_Horizontal )
- arguments of ImPlotGetter have been reversed to be consistent with other API callbacks
- SetupAxisScale + ImPlotScale have replaced ImPlotAxisFlags_LogScale and ImPlotAxisFlags_Time flags
- ImPlotFormatters should now return an int indicating the size written
- the signature of ImPlotGetter has been reversed so that void* user_data is the last argument and consistent with other callbacks
- 2021/10/19 (0.13) - MAJOR API OVERHAUL! See #168 and #272
- TRIVIAL RENAME:
- ImPlotLimits -> ImPlotRect
- ImPlotYAxis_ -> ImAxis_
- SetPlotYAxis -> SetAxis
- BeginDragDropTarget -> BeginDragDropTargetPlot
- BeginDragDropSource -> BeginDragDropSourcePlot
- ImPlotFlags_NoMousePos -> ImPlotFlags_NoMouseText
- SetNextPlotLimits -> SetNextAxesLimits
- SetMouseTextLocation -> SetupMouseText
- SIGNATURE MODIFIED:
- PixelsToPlot/PlotToPixels -> added optional X-Axis arg
- GetPlotMousePos -> added optional X-Axis arg
- GetPlotLimits -> added optional X-Axis arg
- GetPlotSelection -> added optional X-Axis arg
- DragLineX/Y/DragPoint -> now takes int id; removed labels (render with Annotation/Tag instead)
- REPLACED:
- IsPlotXAxisHovered/IsPlotXYAxisHovered -> IsAxisHovered(ImAxis)
- BeginDragDropTargetX/BeginDragDropTargetY -> BeginDragDropTargetAxis(ImAxis)
- BeginDragDropSourceX/BeginDragDropSourceY -> BeginDragDropSourceAxis(ImAxis)
- ImPlotCol_XAxis, ImPlotCol_YAxis1, etc. -> ImPlotCol_AxisText (push/pop this around SetupAxis to style individual axes)
- ImPlotCol_XAxisGrid, ImPlotCol_Y1AxisGrid -> ImPlotCol_AxisGrid (push/pop this around SetupAxis to style individual axes)
- SetNextPlotLimitsX/Y -> SetNextAxisLimits(ImAxis)
- LinkNextPlotLimits -> SetNextAxisLinks(ImAxis)
- FitNextPlotAxes -> SetNextAxisToFit(ImAxis)/SetNextAxesToFit
- SetLegendLocation -> SetupLegend
- ImPlotFlags_NoHighlight -> ImPlotLegendFlags_NoHighlight
- ImPlotOrientation -> ImPlotLegendFlags_Horizontal
- Annotate -> Annotation

- SetNextPlotTicksX, SetNextPlotTicksY -> use SetupAxisTicks
- SetNextPlotFormatX, SetNextPlotFormatY -> use SetupAxisFormat
- AnnotateClamped -> use Annotation(bool clamp = true)
- OBSOLETED:
- BeginPlot (original signature) -> use simplified signature + Setup API
- 2021/07/30 (0.12) - The offset argument of `PlotXG` functions was been removed. Implement offsetting in your getter callback instead.
- 2021/03/08 (0.9) - SetColormap and PushColormap(ImVec4*) were removed. Use AddColormap for custom colormap support. LerpColormap was changed to SampleColormap.
ShowColormapScale was changed to ColormapScale and requires additional arguments.
- 2021/03/07 (0.9) - The signature of ShowColormapScale was modified to accept a ImVec2 size.
- 2021/02/28 (0.9) - BeginLegendDragDropSource was changed to BeginDragDropSourceItem with a number of other drag and drop improvements.
- 2021/01/18 (0.9) - The default behavior for opening context menus was change from double right-click to single right-click. ImPlotInputMap and related functions were moved
to implot_internal.h due to its immaturity.
- 2020/10/16 (0.8) - ImPlotStyleVar_InfoPadding was changed to ImPlotStyleVar_MousePosPadding
- 2020/09/10 (0.8) - The single array versions of PlotLine, PlotScatter, PlotStems, and PlotShaded were given additional arguments for x-scale and x0.
- 2020/09/07 (0.8) - Plotting functions which accept a custom getter function pointer have been post-fixed with a G (e.g. PlotLineG)
- 2020/09/06 (0.7) - Several flags under ImPlotFlags and ImPlotAxisFlags were inverted (e.g. ImPlotFlags_Legend -> ImPlotFlags_NoLegend) so that the default flagset
is simply 0. This more closely matches ImGui's style and makes it easier to enable non-default but commonly used flags (e.g. ImPlotAxisFlags_Time).
- 2020/08/28 (0.5) - ImPlotMarker_ can no longer be combined with bitwise OR, |. This features caused unnecessary slow-down, and almost no one used it.
- 2020/08/25 (0.5) - ImPlotAxisFlags_Scientific was removed. Logarithmic axes automatically uses scientific notation.
- 2020/08/17 (0.5) - PlotText was changed so that text is centered horizontally and vertically about the desired point.
- 2020/08/16 (0.5) - An ImPlotContext must be explicitly created and destroyed now with `CreateContext` and `DestroyContext`. Previously, the context was statically initialized in this source file.
- 2020/06/13 (0.4) - The flags `ImPlotAxisFlag_Adaptive` and `ImPlotFlags_Cull` were removed. Both are now done internally by default.
- 2020/06/03 (0.3) - The signature and behavior of PlotPieChart was changed so that data with sum less than 1 can optionally be normalized. The label format can now be specified as well.
- 2020/06/01 (0.3) - SetPalette was changed to `SetColormap` for consistency with other plotting libraries. `RestorePalette` was removed. Use `SetColormap(ImPlotColormap_Default)`.
- 2020/05/31 (0.3) - Plot functions taking custom ImVec2* getters were removed. Use the ImPlotPoint* getter versions instead.
- 2020/05/29 (0.3) - The signature of ImPlotLimits::Contains was changed to take two doubles instead of ImVec2
- 2020/05/16 (0.2) - All plotting functions were reverted to being prefixed with "Plot" to maintain a consistent VerbNoun style. `Plot` was split into `PlotLine`
and `PlotScatter` (however, `PlotLine` can still be used to plot scatter points as `Plot` did before.). `Bar` is not `PlotBars`, to indicate
that multiple bars will be plotted.
- 2020/05/13 (0.2) - `ImMarker` was change to `ImPlotMarker` and `ImAxisFlags` was changed to `ImPlotAxisFlags`.
- 2020/05/11 (0.2) - `ImPlotFlags_Selection` was changed to `ImPlotFlags_BoxSelect`
- 2020/05/11 (0.2) - The namespace ImGui:: was replaced with ImPlot::. As a result, the following additional changes were made:
- Functions that were prefixed or decorated with the word "Plot" have been truncated. E.g., `ImGui::PlotBars` is now just `ImPlot::Bar`.
It should be fairly obvious what was what.
- Some functions have been given names that would have otherwise collided with the ImGui namespace. This has been done to maintain a consistent
style with ImGui. E.g., 'ImGui::PushPlotStyleVar` is now 'ImPlot::PushStyleVar'.
- 2020/05/10 (0.2) - The following function/struct names were changes:
- ImPlotRange -> ImPlotLimits
- GetPlotRange() -> GetPlotLimits()
- SetNextPlotRange -> SetNextPlotLimits
- SetNextPlotRangeX -> SetNextPlotLimitsX
- SetNextPlotRangeY -> SetNextPlotLimitsY
- 2020/05/10 (0.2) - Plot queries are pixel based by default. Query rects that maintain relative plot position have been removed. This was done to support multi-y-axis.
