Henrik RydgårdandClaude Opus 5.5 a6849661ba Shade mapping: Use the light vector as lighting sees it
Environment map S and T are (N.L + 1) / 2 with L the light's vector as
lighting uses it: from the vertex to the light for point and spot lights,
a zero vector staying zero, and the half vector for a light that does
specular. Whether lighting or the light is enabled still doesn't matter
(gpu/lighting/shademap).

The vertex shader ID now carries the type and computation of the shade
mapping lights (the ubershader reads them from u_lightControl), so both
shader caches get a new version.

Fixes the hair shine in iDOLM@STER SP (#12376).

Henrik RydgårdandClaude Opus 5.5 aa38fafd77 DrawEngine: Don't drop large batches of points, lines and rectangles
Software transform expands each point, line and rectangle to four
vertices, and gave up on the whole draw when that didn't fit
VERTEX_BUFFER_MAX. Batching only counted input vertices, so a batch over
16384 points (or 32768 line or rectangle vertices) vanished silently,
whether it came from one PRIM or several merged ones. Count the expanded
vertices when batching, and submit a PRIM too big on its own in parts.

Henrik RydgårdandClaude Opus 5.5 7a06e25aa0 GPU: Remove leftovers from hardware tessellation
The GLES sampler uniforms and texture slots for the control points and
weights, the Vulkan storage buffer bindings, and the u_spline_counts
uniform, which becomes padding (the C++ side already was).

Henrik RydgårdandClaude Opus 5.5 93f57a4f38 GPU: Delete copy operations on classes that own resources
These own GPU objects, memory or refcounts in their destructors (or assert
there that they were torn down), so a copy would double-free. Nothing copies
them today; this keeps it that way. The manager base classes cover every
backend's subclass.

Henrik RydgårdandClaude Opus 5.5 e108e41675 GPU: Fix assorted leaks, null derefs and small rendering bugs
- Put the anisotropy level in the sampler key, so changing it applies on
  Vulkan and D3D11.
- Release CLUT textures at shutdown on GLES and D3D11.
- Fix the depth readback viewport, which squeezed the image whenever the
  read rectangle was smaller than the fbo.
- Test the computed depth, not the unset result, in the equal-depth clear
  check.
- Don't read back a CLUT from a framebuffer without an fbo.
- Tolerate null entries when releasing post-shader objects and CLUT
  textures after a failed creation.
- ImGe: Don't crash on a framebuffer without an fbo, or on GetVFB under the
  software renderer.

Henrik RydgårdandClaude Opus 5.5 71bc3187db Vulkan: Reload the shader cache after a device restore
DeviceLost saves the cache and clears everything, and the next save wrote
back only what was drawn since, so each Android background/resume cycle
shrank the cache.

Henrik RydgårdandClaude Opus 5.5 16ea2cbf88 GPU: Fix draw engine buffer overruns and stale vertex data
- Flush before the queued draws would decode more than VERTEX_BUFFER_MAX
  vertices. The batch was limited by index count, which doesn't bound a
  sparse index range, and DecodeVerts silently stopped while DecodeInds
  still emitted indices for the undecoded draws.
- Give TestBoundingBox its own scratch buffer. It used offsets in decoded_,
  which can hold decoded vertices that aren't flushed yet.
- Read 32-bit indices the way the PSP does, ignoring the upper 16 bits.
  IndexConverter and the fast bounding box test used all 32, so a game
  setting them indexed far past the decoded vertices.
- D3D11: Flush in FinishDeferred like the other backends, since indices
  are still read from PSP memory at flush time (#10095).
- Don't JIT new vertex decoders once the code space is full.

Henrik RydgårdandClaude Opus 5.5 24b71386ff Document that shader cache key changes need a CACHE_VERSION bump
The OpenGL and Vulkan shader caches store raw shader IDs (and, for Vulkan,
pipeline keys) on disk. Add the rule to AGENTS.md and point to it from the
persisted types.

Henrik RydgårdandClaude Opus 5.5 4df1b9c2c3 Vulkan: Clear pipelines before shaders when use flags change
The pipeline deletion callbacks block on in-flight compiles, which use the
shader module promises that the shaders' deletion callbacks free. Queueing
the shaders first freed the promises under a pending compile.

Henrik RydgårdandClaude Opus 5.5 8b4e93021e Vulkan: Cache compiled SPIR-V so shaders skip glslang on later runs
GLSLtoSPV takes an optional SPIRVCache, keyed on a 32-bit hash of the
source, stage and variant, plus the source length. A changed shader
simply misses. thin3d's shaders and the other fixed ones use a global
cache in PSP/SYSTEM/CACHE/vulkan_spirv.cache, loaded on first use and
saved after graphics init, when a game's cache is saved, and at
shutdown; it's flushed once it reaches 32 entries, about twice what a
session compiles, so outdated ones don't pile up. Game shaders keep
theirs in the .vkshadercache, ahead of the shader IDs so that the
compiles on load find it (version 60), and only what the session used
is saved.

A cold glslang costs about 40ms before its first shader here, and
0.3-0.9ms per shader after that.

Henrik RydgårdandClaude Opus 5 859d09cc75 Vulkan: Two small fixes
The pipeline debug listing printed the color blend factors in the alpha slot,
which is doubly unhelpful since that branch is only taken when the alpha factors
differ from the defaults.

CompileShaderModuleAsync takes ownership of the tag but only deleted it on the
success path, leaking it whenever GLSLtoSPV failed.

Henrik RydgårdandClaude Opus 5 9273764a3b Vulkan: Don't insert the same key twice when compute pipeline creation fails
The failure branch inserted a null pipeline and then fell through to the normal
insert of the same key, which trips DenseHashMap's duplicate-key assert - and
_assert_msg_ is live in release builds, so a logged error became a crash.

Also skip the null entries when deleting cached pipelines.

Henrik RydgårdandClaude Opus 5 41d69e61e1 Vulkan: Set USES_DEPTH_STENCIL/USES_BLEND_CONSTANT before creating the pipeline
They were OR-ed into pipelineFlags just after the CreateGraphicsPipeline call that
consumes them, so the render manager's "don't compile a pipeline that requires
depth for a non-depth renderpass type" check could never fire for game pipelines.
thin3d_vulkan.cpp sets the flag before its call, which is the intended order.

Note this can now legitimately skip some variants when loading the shader cache -
those were invalid combinations that the check was written to reject.

Henrik RydgårdandClaude Opus 5 38d5ab657e Vulkan: Disable hardware texture scaling if the constant buffer fails to load
If reading the shader's constant buffer file failed, we'd skip writing descriptor
binding 4 but still dispatch the compute shader, which declares it - a statically
used but unwritten descriptor. It also re-read the missing file on every single
texture upload. Now we drop the scaling shaders instead, so following textures
take the CPU scaling path.

Henrik RydgårdandClaude Opus 5 79a48c7dbe Vulkan: Fix crash when a replaced texture fails to allocate
The out-of-VRAM retry path cleared plan.replaced but left plan.doReplace set.
GetMipSize() dereferences plan.replaced when doReplace is true, so the fallback
crashed instead of recovering. The common code sets both together.

Henrik Rydgård de0dc2d7d4 Remove the leftover geometry shader scaffolding
Nothing has generated or used a geometry shader since the GS paths were removed
- GeometryShaderGenerator is gone, and ShaderWriter's BeginGSMain/EndGSMain had
no callers at all. Removes ShaderStage::Geometry and everything hanging off it:
the GS preambles and GSMain helpers in ShaderWriter, the stage mappings in all
three thin3d backends, the D3D11 geometry shader plumbing (curGS_, the pipeline
and module members, gs_4_0 compilation), CreateGeometryShaderD3D11, the unused
PipelineFlags::USES_GEOMETRY_SHADER and PipelineManagerVulkan's
UsesGeometryShader().

Also stop enabling the Vulkan geometryShader device feature, since we no longer
have any use for it.

Kept on purpose: the device feature is still listed in the feature dumps (like
other capabilities we don't use), and the Vulkan shader cache header keeps its
now-always-zero geometry shader count so the on-disk format stays compatible.
