I haven't looked much into what actually happens now, but the last
time I looked at using renderbuffers for FBO attachments, one of the
issues that came up was the initial surface contents. Right now we
handle that by clearing WINED3D_LOCATION_SYSMEM and marking it
current, but that won't work so well for renderbuffers. Somewhat
related, does WINED3DFMT_D16_LOCKABLE need special handling?
