PointInRect error (maybe?)

The current function reads:

inline bool RectI::pointInRect(const Point2I &pt) const
{
   return (pt.x >= point.x && pt.x < point.x + extent.x && pt.y >= point.y && pt.y < point.y + extent.y);
}

Shouldn't it read:

inline bool RectI::pointInRect(const Point2I &pt) const
{
   return (pt.x >= point.x && pt.x <= point.x + extent.x && pt.y >= point.y && pt.y <= point.y + extent.y);
}

I just added "=" signs to the "pt < point + extent" conditions.

Just a thought
