Phase O Task 3 — verbatim-copy GL infra from Chorizite.OpenGLSDLBackend
into src/AcDream.App/Rendering/Wb/ (namespace AcDream.App.Rendering.Wb).
18 files extracted (all namespace-changed; no algorithm changes):
OpenGLGraphicsDevice, ManagedGLTexture, ManagedGLTextureArray,
ManagedGLVertexBuffer, ManagedGLIndexBuffer, ManagedGLVertexArray,
ManagedGLFrameBuffer, ManagedGLUniformBuffer, GLSLShader, GLHelpers,
GLStateScope, GpuMemoryTracker, SceneData, DebugRenderSettings,
TextureParameters, TextureFormatExtensions, BufferUsageExtensions,
EmbeddedResourceReader.
3 internals promoted to public (O-D9):
EmbeddedResourceReader, TextureFormatExtensions, BufferUsageExtensions.
SixLabors.ImageSharp not reachable: TextureHelpers was placed in
AcDream.Core (no GL/ImageSharp dep); only the GL types went to App.
TextureHelpers.GetCompressedLayerSize added to AcDream.Core.Rendering.Wb
(was in Chorizite.OpenGLSDLBackend.Lib.TextureHelpers; uses
Chorizite.Core.Render.Enums.TextureFormat which Core gets transitively
via the still-present WB project refs).
T3/T4 boundary interims:
- WbMeshAdapter._graphicsDevice stays Chorizite.OpenGLSDLBackend.OpenGLGraphicsDevice
(T4 will swap it when ObjectMeshManager is extracted).
- OpenGLGraphicsDevice.ParticleBatcher deferred to null! (T4 extracts
ParticleBatcher alongside ObjectMeshManager; can't pass `this` of our
new type to the WB-original ctor before T4).
- ManagedGLTextureArray uses our TextureHelpers via explicit alias.
- IUniformBuffer is in Chorizite.Core.dll under Chorizite.OpenGLSDLBackend
namespace (unusual packaging); resolved via type alias.
- AcDream.App.csproj gets explicit Chorizite.Core 0.0.18 PackageReference
(IUniformBuffer + other Chorizite.Core types now used directly in App).
Build green. Test baseline 1147+8 maintained (1902 passing, 8 pre-existing
MotionInterpreterTests failures unrelated to T3).
