- Add e2e cases for gpu-instancing-auto-batch and gpu-instancing-custom-data - Add all missing matrix uniform types (mat2, mat3, mat2x3, mat2x4, mat3x2, mat3x4, mat4x2, mat4x3) to ShaderUniform and ShaderProgram - Skip UBO members (location === null) in uniform reflection - Restore throw for truly unsupported uniform types in default branch
