We want to be able to have compositors with different backends living at the same time, so it doesn't make sense to have a global compositor backend.

To achieve this we need to make sure that there is a 1-1 mapping between SurfaceDescriptor and TextureHost, so that we don't need to know about the backend to create the TextureHost.

- SurfaceDescriptorD3D10 can make either a D3D11 or a D3D9 TextureHost
- SurfaceDescriptorMacIOSurface can make either a Basic or a GL TextureHost.

In the case of MacIOSurface, the backend part should be moved into the TextureSource, while making the TextureHost independent of GL/Software. Not sure about SurfaceDescriptorD3D10.
