NULL is pretty special, and will require changes in a number of
places. Maybe it shouldn't go through the regular surface creation
path at all. Note that the point of the series is to disallow creating
surfaces with a zero width or height; failing NVDB surface creation is
just a fortunate side effect. In the longer term we should also
disallow e.g. formats without a GL format for resources in the default
or managed pools.
