The resource manager factory methods will use ClearView or zero-filled
buffers to set initial data. It assumes there are no 3D depth/stencil
textures. This will lead to some wasteful re-creation of RTVs in some
cases.
This is a temporary measure until we can implement more efficient
lazy resource init strategies.
