SQLite: Valid extents not being returned.

[jbirch]

Not sure if this is a bug or an enhancement request...

In order for a Layer to be previewed in MapGuide, valid data extents need to be known. I'm not sure if this information is pulled from the spatial context, or a separate call.

In any case, it is not working with this provider, and it makes it difficult to see what you're working with in MapGuide until you get the layer into a map with either other known-extent layers, or manually set map extents.

If you're willing to add this capability to the provider, I can do a bit of research and see where Studio is getting its extents info from.
