Check if point aP lies inside a closed shape.

Always returns false if this shape is not closed.

Parameters

aPt	point to check
aUseBBoxCache	gives better performance if the bounding box caches have been generated.

Returns: true if the point is inside the shape (edge is not treated as being inside).
