Render actual 3D geometry (cubes + ground plane) in the Viewport panel
using the existing mesh_shader.wgsl Blinn-Phong pipeline with orbit
camera controls (left-drag to orbit, middle-drag to pan, scroll to zoom).

Add full-frame-cycle integration test to dock.rs (16 tests total) and
update editor_demo to use DockTree layout instead of a single panel.

Add IMGUI HUD overlay showing HP, wave, score, and enemy count.
Display centered Game Over panel with final score and restart prompt.
Add procedural sine-wave audio clips for shooting (440Hz) and enemy
kills (220Hz) via voltex_audio. Player blinks white during invincibility.
Press R to restart after game over.

Projectiles destroy enemies on contact (radius check 0.55). Enemies
damage the player on contact with 1s invincibility window. Score +100
per kill. Game over when HP reaches 0. update() now returns FrameEvents
so the caller can trigger audio/visual feedback.

Red sphere enemies spawn at arena edges via a wave system that
escalates each round. Enemies use direct seek steering to chase
the player. Both shadow and color passes render enemies.

Left click fires small yellow sphere projectiles from the player toward
the mouse cursor position on the XZ plane. Includes fire cooldown (0.2s),
projectile lifetime (2.0s), and ray-plane intersection for mouse aiming.

Add blue sphere as the player with WASD movement on XZ plane,
clamped to arena bounds. Camera now tracks player position.
Pre-allocate dynamic UBO buffers for 100 entities to support
future enemies and projectiles.

Static arena with 20x20 floor and 4 box obstacles rendered using the
forward PBR pipeline with shadow mapping. Fixed quarter-view camera
at (0, 15, 10) looking at origin.

Interactive demo showing panel, text, button, slider, and checkbox
widgets rendered via the new UiRenderer pipeline. Uses winit event
loop with mouse input forwarded to UiContext.

- Add 'enable wgpu_ray_query' to RT shadow shader
- Fix RayDesc struct constructor syntax and rayQueryGetCommittedIntersection API
- Enable ExperimentalFeatures in GpuContext for RT
- Change RT shadow texture binding to non-filterable (R32Float)
- Use textureLoad instead of textureSample for RT shadow in lighting pass

Lighting pass now renders to Rgba16Float HDR target. A 5-level bloom
mip chain (downsample with bright-extract threshold, then additive
upsample) feeds into an ACES tonemap pass that composites the final
LDR output to the swapchain surface. All resources resize correctly.

Integrate BLAS/TLAS acceleration structures and RT shadow compute pass
into the deferred rendering demo. Adds GpuContext::new_with_features()
for requesting EXPERIMENTAL_RAY_QUERY, Mesh::new_with_usage() for
BLAS_INPUT buffer flags, and extends the lighting shadow bind group
to 9 entries (shadow map + IBL + SSGI + RT shadow).

Demonstrates two-pass deferred rendering: G-Buffer pass writes position,
normal, albedo, and material to 4 render targets; lighting pass composites
with 8 animated orbiting point lights plus a directional light using a
fullscreen triangle.

wgpu's default max_bind_groups is 4 (groups 0-3), but the PBR shader was
using group(4) for BRDF LUT bindings. This merges IBL bindings into the
shadow bind group (group 3) at binding slots 3-4, removes the standalone
IBL bind group layout/creation, and updates all examples accordingly.

Fix pbr_demo, multi_light_demo, and shadow_demo to use the new 7-param
create_pbr_pipeline with PBR texture bind group (4-entry: albedo+normal)
and IBL bind group. Create ibl_demo showcasing a 7x7 metallic/roughness
sphere grid with IBL-based ambient lighting via BRDF LUT integration.

- Add Mat4::orthographic() to voltex_math for light projection
- Fix pbr_demo and multi_light_demo to provide shadow bind group (group 3)
required by updated PBR pipeline (dummy shadow with size=0 disables it)
- Create shadow_demo with two-pass rendering: shadow depth pass using
orthographic light projection, then PBR color pass with shadow sampling
- Scene: ground plane, 3 spheres, 2 cubes with directional light

Fix pbr_demo to use LightsUniform/LightData instead of old LightUniform.
Create multi_light_demo with 5 PBR spheres (varying metallic), a ground
plane, 4 colored orbiting point lights, a directional fill light, and a
spot light from above.

7x7 grid of spheres demonstrating PBR material variation:
metallic increases along X axis, roughness along Y axis.
Uses dynamic UBO pattern for both camera and material uniforms.

Previous approach called write_buffer inside render pass which doesn't
work — GPU only sees the last value at submit time. Now pre-computes all
entity uniforms into a dynamic UBO and uses dynamic offsets per draw call.
