b26b9cf743 Add Vulkan rendering backend, with HDR10 output and raytraced shadows (#7554)
* Shadow overhaul round 2: PCSS, dynamic cascades, cockpit/instanced shadows

Squashed snapshot of lafiel/shadow_overhaul_2's continuation work
(d3922aa87..010f9d2d9), which has no separate upstream PR of its own.

* Add Vulkan rendering backend

Squashed snapshot of the Vulkan backend as vendored into this branch
(ce2d1e85f..6ce539463, authored by Mara van der Laan with build/CI
fixes by Taylor Richards). This work has its own upstream PR #7553
(notimaginative:vulkan-pr-new) and is not otherwise original to true-hdr.

* Add true HDR output, RT shadows, and PCSS shadows for Vulkan

Squashed snapshot of true-hdr's own integration work: true HDR
framebuffer output, wiring the shadow overhaul into the Vulkan
backend (raytraced + cascaded shadow maps), logging refactors, log
filter UI, and CI/build fixes.

* refactor: update Vulkan logging calls to use `nprintf` for scoped logging

* fix: correct shadow cascade count in Vulkan logging calls

* fix: fall back to PATH-resolved ccache when CCACHE_PATH is stale

CI hardcodes /usr/local/bin/ccache, but macOS runners on Apple Silicon
hosts install Homebrew (and ccache) under /opt/homebrew instead,
causing all four Mac configs to fail with "No such file or directory".

* Fix vulkan texture readback to correctly handle transparent pipelines

* Put the pixel swizzles into a util file

* OOB safety check

* Fix fog handling

* Fix MSAA in Vulkan

* fix: enable SMAA for vulkan

* adapt the post-processing AA shaders to hdr

* fix clang-tidy warnings: concatenate nested namespaces, static methods

pixel_swizzle.{h,cpp}: collapse `namespace graphics { namespace util {`
into `namespace graphics::util {` (modernize-concat-nested-namespaces).

VulkanState.h/VulkanDraw.h: getClearColor()/setClearColor() only touch
gr_screen and other globals, no instance state, so make them static
(readability-convert-member-functions-to-static) and drop the
top-level const on getClearColor()'s return type
(readability-const-return-type).

* fix clang-tidy warning

* Extend raytraced shadows to all directional lights

RT shadows previously only shadowed the first directional light in the
scene, even though multi-sun missions push more than one directional
light into the engine. The TLAS raytraced shadows query against is
already light-agnostic, so this extends both the deferred lighting
pass and the forward MODEL shader to shadow every directional light
(capped by a new Max Raytraced Shadow Lights option, configurable via
the in-game Options menu or the Lab's Scene rendering options).

Cascaded shadow maps are untouched: they're built for a single light
only, so the deferred pass still limits itself to one shadowed
directional light whenever CSM (not raytracing) is the active method.

* refactor: improve shader flag handling and render target finalization in Vulkan backend

- Consolidate shader flag setup logic in VulkanPostProcessingLighting to simplify configuration.
- Fix dead field usage in VulkanDraw by ensuring correct image view selection for environment maps.
- Add mip chain regeneration in VulkanRenderer::endRenderTarget to ensure correct mip levels for cubemaps.

* fix: ensure correct mip chain initialization in cubemap rendering

- Add mip chain generation to VulkanDraw for cubemaps with multiple mip levels.
- Fix potential issue with uninitialized mip levels above level 0 in deferred-f.sdr sampling paths.

* fix: don't crash on startup when environment locale is unavailable

std::locale("") pulls in the process's environment locale categories
(LC_CTYPE, LC_MONETARY, LC_PAPER, etc.), and throws std::runtime_error
if any of them names a locale not installed on the host (e.g.
mismatched regional-format overrides). Since SCP_default_locale is
constructed during static initialization, before main() and before any
of our own exception handling exists, an uncaught throw here aborted
the whole process before the game even started. Fall back to the
classic "C" locale instead, which is sufficient since this locale is
only ever used for ASCII case-folding (SCP_toupper/tolower/isdigit).

- Refactored VulkanPostProcessor and associated shaders to support gamma slider adjustments for both SDR and HDR output.

* fix: ensure proper uniform and cull mode setup for Vulkan sphere rendering

- Added uniform buffer setup and default material uniforms in `vulkan_draw_sphere`.
- Disabled face culling in material definition for sphere rendering to align behavior with OpenGL.

* Ensure memory flushes after UBO updates and add explicit pipeline barrier for MoltenVK compatibility.

* fix: add clear pass for SMAA edge detection to prevent persistent artifacts

* feat: add Vulkan debug-utils messenger, opt-in sync validation, frame diagnostics

Groundwork for the renderer-review fix series (.agents/plans/
vulkan-renderer-review-fixes.md, Phase 0):

- Register a VK_EXT_debug_utils messenger (preferred) instead of only the
  deprecated VK_EXT_debug_report callback, which is kept as a fallback for
  loaders without debug-utils. The messenger config is also chained into
  instance creation so vkCreateInstance-time messages are captured.
  Validation errors/warnings now go to the main log via mprintf.
- New -gr_sync_validation cmdline flag (implies -gr_debug): chains
  VkValidationFeaturesEXT with synchronization validation into instance
  creation when VK_LAYER_KHRONOS_validation is available. This is the
  regression net for the synchronization fixes in the following commits.
- Frame stats now report descriptor sets/writes allocated per frame and the
  total pipeline count (descriptor-manager counters; DescriptorWriter::flush
  moved out-of-line to report into the manager).

* refactor: unify Vulkan render-pass begins, clamp in-pass clears, add per-frame UBO ring

Phase 1 of the renderer-review fix series: shared helpers that the
correctness fixes build on.

- New VulkanRenderer::beginTrackedRenderPass(PassBeginDesc): every render-pass
  begin on the frame command buffer now records vkCmdBeginRenderPass and
  updates the state tracker (pass, color attachment count, sample count,
  render area, viewport) in one place. Converted: setupFrame,
  beginSceneRendering (both branches), resumeSceneRendering,
  endSceneRendering, beginRenderTarget (viewport kept for gr_set_viewport),
  resumeSwapChainPass, plus new resumeScenePassAfterCopy() shared by
  copyEffectTexture/copySceneDepthForParticles and
  rebeginSwapChainPassAfterReadback() shared by both readbackFramebuffer
  exits (~200 lines of duplicated begin/clear/viewport blocks removed).
- The state tracker records the active render area; all four
  vkCmdClearAttachments sites clamp their rects against it and skip empty
  results. Previously gr_screen-sized clear rects could exceed a smaller
  off-screen render target's render area, which is invalid API usage.
- New PerFrameUboRing utility (VulkanPerFrameUbo.h/.cpp): a persistently
  mapped uniform buffer with one slot region per frame in flight and a
  self-flushing alloc(). Used by the next commit to fix the cross-frame
  UBO races.

Deliberate behavior deltas (all safe-direction): the helper always sets
colorAttachmentCount/sampleCount (some sites previously inherited stale
values), and resumeSwapChainPass/resumeSceneRendering now also reset the
standard flipped viewport instead of leaving the previous one.

* fix: eliminate Vulkan cross-frame UBO/buffer races, make gr_sync honest

Phase 2 of the renderer-review fix series: with two frames in flight, several
host-visible resources were rewritten by the CPU while the previous frame's
GPU work could still be reading them.

- The post-processing scratch UBO is now a PerFrameUboRing (per-frame-in-
  flight slot regions, persistently mapped, self-flushing alloc). All the
  per-pass map/unmap/cursor bookkeeping in bloom/LDR/fog/SMAA is deleted;
  the cursor resets exactly once per frame via the new
  VulkanPostProcessor::beginFrame() hook in setupFrame.
  This also fixes two latent bugs: (a) fog consumed scratch slots mid-scene
  and bloom's later same-frame cursor reset overwrote them before submission
  whenever fog+bloom were both active; (b) volumetric_fog_data (288 bytes)
  overflowed the 256-byte slots - the memcpy spilled into the neighboring
  slot and the shader's bound range ended before the aspect/fov/noise
  fields. Slots are now 512 bytes (static_assert at the fog call site) and
  the per-frame budget is 32 slots.
- The dedicated tonemap, output-encode, and MSAA-resolve UBOs (each a single
  instance rewritten per frame, i.e. racy; the MSAA one also never flushed)
  are deleted entirely - those passes build their structs on the stack and
  allocate from the scratch ring.
- Static-buffer rewrites orphan instead of racing: getVkBuffer() stamps a
  last-used frame number, and a full-content updateBufferData() on a Static
  buffer used within the last MAX_FRAMES_IN_FLIGHT frames defers the old
  VkBuffer to the deletion queue and writes a fresh one. Offset writes
  (GPU-heap appends to fresh regions) and PersistentMapping buffers (the
  engine holds their mapped pointer and syncs via gr_sync) are exempt.
- gr_sync_wait now honors its contract: VulkanRenderFrame::waitForFinish
  takes a timeout and reports expiry without consuming the fence;
  VulkanRenderer::waitForFrame returns false for fences taken during the
  still-recording frame (previously it waited on a stale or idle slot and
  reported success) and resolves the frame->slot mapping correctly. This
  makes UniformBufferManager's segment-fence throttling actually protective
  on Vulkan for the first time.

- Implemented precise input tracking for Material and PerDraw descriptor sets to detect and rebuild only when necessary.
- Reduced redundant Vulkan descriptor allocations and writes, improving performance on repeated or batched draw calls.

* Fix Vulkan access masks for G-buffer and scene pass transitions

- Added `eColorAttachmentRead` to access masks in multiple barriers to ensure proper synchronization for load operations (e.g., `loadOp=eLoad`) across render passes.
- Prevented `READ_AFTER_WRITE` synchronization validation issues in deferred and multi-pass rendering scenarios.
- Updated comments to clarify the reasoning behind the access mask changes and load dependencies.

* Refactor Vulkan resource management and indexed draw logic

- Consolidated destruction queue methods in `VulkanDeletionQueue` using a shared `queueHandle` template to reduce redundancy.
- Introduced `ModelDrawParams` structure and `computeModelDrawParams` function to unify indexed draw parameters for models and shadows.
- Simplified draw logic by eliminating repeated calculation of indexed draw parameters and improving code reuse.

* Add `releaseAnimationSlotRef` for ref-count handling of shared animation texture arrays

- Introduced `releaseAnimationSlotRef` to manage reference counting for shared animation texture-array slots, preventing premature destruction of shared resources.
- Updated `flushTextures` and related methods to integrate `releaseAnimationSlotRef` for shared slot cleanup.
- Refactored staging buffer creation into `createStagingBuffer` for 3D texture uploads and shared path consistency.
- Enhanced texture upload logic with improved tracking and logging for re-upload cases, aiding preloading gap analysis.

Goober5000andClaude Opus 4.8 bed228d264 avoid undefined behavior from UNREACHABLE on reachable code paths (#7555)
* avoid undefined behavior from UNREACHABLE on reachable code paths

UNREACHABLE expands to __assume(false) / __builtin_unreachable() in
release builds, which is undefined behavior if the code is ever actually
reached. Many UNREACHABLE sites only guard against unexpected-but-
possible runtime states (values from tables, mission/save files, network
packets, scripting, or user input), so reaching them should degrade
gracefully rather than invoke UB.

Replace UNREACHABLE with Assertion(false, ...) at all such sites. It
still pops an error in debug builds, but in release it is a harmless
no-op that simply falls through to the following code. Sites that are
genuinely unreachable by local invariants (e.g. a switch over a bounded
random number) are left as UNREACHABLE.

A few converted sites had no safe fall-through -- an uninitialized read,
null dereference, or null call would have followed -- so they also get a
minimal recovery: initialize the value, guard the dereference, return
early, or skip the offending item.

Where the converted site was a simple guard of the form
    if (x) { Assertion(false, ...); return; }
hoist the check onto the invariant instead:
    Assertion(!x, ...);
    if (x) { return; }
This states the expectation directly and shows the offending value in
the debug popup, while keeping the same graceful runtime degradation.

Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

* addendum

After consultation with Lafiel, use UNREACHABLE in situations that are effectively impossible even if not provably impossible.  UNREACHABLE = "this shouldn't ever happen"; Assertion = "if this ever happens, it's a coding error".  Also fix a few other sites and change a couple to Warnings.

Taylor Richards d6c1b36c56 fix issues with imgui backend/renderer cleanup (#7278)
If the graphics system fails to fully init for some reason then it's possible
for the imgui backend and/or renderer to not be initialized. Those subsystems
*must* be initialized before being shut down so we need to check for that to
avoid hitting assertions inside of imgui.

Also add a safety check for making sure that an imgui context exists before
attempting to initialize the backend/renderer. A simple assertion should work
for this as it would take a coder messing something up in order to trip it.

asarium 2f3f061e75 Add Vulkan instance and surface creation code
This adds a new graphics type for the Vulkan graphics API. All this does
is to create a vulkan instance and a presentation surface with the help
of SDL.

asarium ad1ede7b74 Add new options system
This is a system for storing arbitrary data in the config file and then
easily retrieving it later on. This has full Lua support for exposing
the available options in a custom UI and changing the values of the
options. This ported some of the existing command line options over to
the new system which is opt-in for the moment by using a mod_table flag.

asarium 39ab45dc7c Add macro for marking unreachable code
This can be used for mark parts of the code which should be unreachable
in normal execution. In debug mode, if such a statement is reached an
Error dialog is shown which aborts the execution. In release mode the
macro is replaced with a compiler specific expression that lets the
compiler know that this part is unreachable which allows it to optimize
the code better.

asarium 4d7324dddf Fix rendering on high DPI displays on Mac
I added the "allow high DPI windows" SDL-flag while investigating #998
but since that flag isn't used on Windows we can safely remove it again
without causing issues.

asarium 6b62146388 Add a Windows executable manifest to FreeSpace2
This sets the dpiAware flag which should improve the compatibility with
High-DPI displays. It also sets a few values for specfying what Windows
versions we support and it also enabled the nicer dialog boxes which
makes the error and warning dialogs look a bit nicer.

asarium 6c1d5263f1 Create main window at 0,0 if its the same size as the display
This fixes #1051 by explicity telling SDL to create the window in the
display corner instead of centering the window. This has caused some
problems because the window borders aren't visible anymore in this case
which lead to some confusion.

asarium 25fa3543f2 Fix a few minor issues with the new debug window
This makes the debug window resizable and also reduces the default size
to ~80% of the used display. This also makes sure that the main window
has input focus after the debug window was created.

niffiwan c6c4f54f79 Remove MSAA
Reasons being; it's incompatible with FXAA, it's slow, and it's causing
OGL init to fail on certain systems. Oh, and it probably doesn't work
anyway :)

asarium efdd4fae68 Add interface for viewport management
This separates OpenGL context creation from window creation and also
allows to implement multiple viewports in the future.

asarium 0bf5ba092b Add interface for creating an OpenGL context
This allows to use a different method of creating and managing the
OpenGL context. This is needed of wxFRED where the OpenGL context is
created by wxWidgets. This will probably also fix #753 since it uses the
old wgl based method of creating an OpenGL context in FRED.
