bool StationRect::PtInExtendedRect ( int  x,
int  y,
int  distance = 0 
) const

Determines whether a given point (x, y) is within a certain distance of the station rectangle.

Note:
x and y are in Tile coordinates
Parameters:
x X coordinate
y Y coordinate
distance The maxmium distance a point may have (L1 norm)
Returns:
true if the point is within distance tiles of the station rectangle
