- Add VertexAttributeType and VertexAttributeNormalized enums in OpenGLVertexArray.h - Add ToGLAttributeType() converter in OpenGLVertexArray.cpp - Remove glActiveTexture() call from quad test (already handled by texture.Bind()) - Remove #include <glad/glad.h> from triangle test - Update unit tests to use encapsulated enums All three OpenGL integration tests (minimal, triangle, quad) pass with 0% pixel difference.
