Comment (by edzimmerman):

 I attached a package containing an example map. To reproduce the defect
 1) Apply the attached package.
 2) In MapGuide Studio, create a fusion web layout referencnig the sample
 map contained in the package.
 3) Launch the web browser on fusion web layout url.
 4) Set layer visibility as follows: airprt020 (OFF); airprt020 filtered
 (ON); Sample_World_Countries (ON).
 5) Do a window select around some points.

 Before the fix, the selection will fail. After the fix, it will succeed.
 The problem was that use of the $filter variable in Query.php was being
 overloaded to both store the possible incoming sql filter and to store the
 possible combined filter of the sql filter and the layer's feature filter.
 I fixed this be adding a new $combinedFilter variable to eliminate the
 overloaded use of $filter.
