 OGC 06-042 section 7.3.3.6[[BR]]
 If a request contains a BBox whose area does not overlap at all with the
 <!BoundingBox> element in the service metadata for the requested layer,
 the server shall return empty content (that is, a blank map or an graphic
 elemenet file with no elements) for that map. Any features that are partly
 or entirely contained in the Bounding Box shall be returned in the
 appropriate format.

 According to OGC WMS specification, MapGuide should apply a spatial filter
 on the request layers. Features out of the <Boundingbox> which specified
 by users should not appear on the WMS layer.

 This might bring MapGuide some performace issues, so I also optimized the
 process: if the request boundingbox within the user specified
 boundingbox, no spatial filter will be applied.
