Method GetSubCells
GetSubCells(IShape)
Like GetSubCells() but with the results filtered by a shape. If
that shape is a IPoint then it must call
GetSubCell(IPoint). The returned cells
should have ShapeRel set to their relation with
shapeFilter. In addition, IsLeaf
must be true when that relation is WITHIN.
Precondition: Never called when Level == maxLevel.
