wip: OpenGL backend — pinned buffers, void* offsets, manual swap
...
- GCHandle.Alloc(Pinned) for BufferData to prevent GC relocation
- void* null for VertexAttribPointer offsets
- ShouldSwapAutomatically=false, manual SwapBuffers
- Solid color debug shader active
- Still has rendering issues — needs visual debugging

fix: column-major matrix copy for OpenGL
...
CopyMatrixToBuffer now transposes during copy (column-major output),
UniformMatrix4 uses transpose=false. Fixes garbage rendering.

fix: transpose matrices for OpenGL (row-major → column-major)
...
System.Numerics.Matrix4x4 is row-major, OpenGL UniformMatrix4 with
transpose=false expects column-major. Changed all UniformMatrix4 calls
to transpose=true. Also explicitly enable depth test + disable cull face
for main pass. Fixes strobe/flickering issue.

feat: Silk.NET OpenGL backend compiles — full shadow mapping support
...
- Fixed all Silk.NET 2.21 API issues:
- BufferData with void* + fixed blocks
- UniformMatrix4 with float[] buffer (CopyMatrixToBuffer helper)
- DrawBuffer/ReadBuffer with DrawBufferMode/ReadBufferMode
- Clear with (uint) cast
- Input delegates: KeyDown(IKeyboard,Key,int), MouseDown(IMouse,MouseButton), Scroll(IMouse,ScrollWheel)
- GetProgram with ProgramPropertyARB
- IWindow alias SilkWindow to avoid ambiguity
- OpenGLRenderer: shadow FBO with depth texture, PCF 3x3, full PBR shader
- OpenGLRenderContext: Silk.NET window + GL context
- OpenGLBackendRegistrar registered as 'opengl'
- 66/66 tests, 0 errors

wip: Silk.NET OpenGL backend — project structure, partial implementation
...
- Engine.Graphics.OpenGL project with Silk.NET.OpenGL, Windowing, Input
- OpenGLWindow (Silk.NET.Windowing), OpenGLInputState (Silk.NET.Input)
- OpenGLRenderer: full shader pipeline with shadow mapping, VAO/VBO upload
- OpenGLRenderContext, OpenGLBackendRegistrar
- Build errors due to Silk.NET 2.21 API differences — needs API investigation
- Raylib and Vulkan backends unchanged
