Dude, Direct3D is a renderer, along with OpenGL. Basically what your saying is you may not use any library that advertises itself as 3D, which is completely unfair to us that don't program in 2D. Before you make assumptions, look at the Ogre source. It's basically just a thin abstraction of OpenGL and DirectX.
So next time, think before you become an ass-umer.
I don't know, I only have a degree in computer science in which I concentrated on graphics, but I always thought there was a distinct difference between a 3D Graphics API and a full featured Graphics Engine.
But yes, you're right, features like "Skeletal animation, including blending of multiple animations, variable bone weight skinning, and hardware-accelerated skinning", a scene graph manager, and a powerful plugin system that easily includes full featured terrain engines, etc. are just a thin wrapper over OGL and D3D.
