- Replace glViewport() with commandList.SetViewport()
- Replace glClearColor()+glClear() with commandList.Clear()
- Add OpenGLCommandList include and instance
- Create TEST_SPEC.md with OpenGL test hierarchy and specifications
- Add section and inline comments to main.cpp explaining:
- Window size calculation with AdjustWindowRect
- glFinish before screenshot for GPU sync
- Target frame count warm-up period
- Shutdown order (reverse of initialization)
- OpenGLSwapChain::Initialize now uses AdjustWindowRect before SetWindowPos
- This ensures window client area matches expected size (1280x720)
- Previously SetWindowPos was given client area size instead of full window size
- Removed debug fprintf statements from OpenGLDevice
- Updated minimal integration test to use cleaner code
- Simplify OpenGL integration test structure
- Enable CTest registration for OpenGL tests
- Refactor test fixtures and device enumeration
- Minor code cleanup and improvements
- Add OpenGL_Minimal integration test using Win32 native API + glad
- Copy run_integration_test.py and compare_ppm.py from D3D12
- Create minimal/main.cpp with red clear color (matching D3D12)
- Generate GT.ppm golden template for 1280x720 red window
- Add VertexArray_Bind_MultipleAttributes unit test
- Update integration/CMakeLists.txt to build OpenGL_Minimal target
