Did we change this so that it could be handled by the hash fn?

No. The spec is indicating the range for this field is int. It should have been
int from the beginning. Long type was incorrect.

     double width() const { return m_width; }
     double height() const { return m_height; }
     float pressure() const { return m_pressure; }

     long tiltY() const { return m_tiltY; }
     const String& pointerType() const { return m_pointerType; }
     bool isPrimary() const { return m_isPrimary; }
