OpenGL on top of DirectX

From what I understand, many more graphics cards have hardware acceleration support for DirectX than for OpenGL. However, I read that some company was implementing the OpenGL library as a wrapper around DirectX to get more hardware acceleration support for OpenGL. I can’t figure out where I read this or who is doing this. Can someone give me more info please? Thanks.
