The inconvenient thing about
wined3d_device_update_sub_resource is that the source data is in a
pointer and not a system memory resource. You can of course just map
the source resource in the client library and pass the map pointer to
wined3d_device_update_sub_resource, but that'll require copying the
data or waiting with the multithreaded command stream.
