François,

I believe this time also includes the data fetching (which is interleaved
with the rendering).  It does not include the time to render labels
deferred till after all layers.  I don't think it is possible to establish
the time for data fetching since it is interleaved with the rendering.  That
is, DrawLayer() fetches a shape, draws it, fetches the next, draws it, etc.
