MiniEngine: Frustum::ConstructOrthographicFrustum near/far plane normals point outward, inconsistent with side planes

https://github.com/microsoft/DirectX-Graphics-Samples/blob/master/MiniEngine/Core/Math/Frustum.cpp I assume the engine uses a righthanded coordinate system, therefore the definition of the plane normals in function void Frustum::ConstructOrthographicFrustum is inconsistent with this convention. Instead of pointing inward, the normals point outward. m_FrustumPlanes[kNearPlane] = BoundingPlane( 0.0f, 0.0f, 1.0f, -Front ); m_FrustumPlanes[kFarPlane] = BoundingPlane( 0.0f, 0.0f, -1.0f, Back ); The z values of these planes should be -1.0f and 1.0 respectively.
