Sure. The wined3d_box structure is a little larger than needed for
buffers though, and in case of buffers it's used largely internally,
so I think an argument could be made for keeping the texture interface
separate (but consistent) in this case. But regardless of what
decision is made there, I think it would be undesirable for buffers to
have dirty regions in both struct wined3d_resource and struct
wined3d_buffer.

No concrete plan.
