Methods:

Line2dIterC(const Index2dC & start,const Index2dC & end): Constructor.
void First(const Index2dC & start,const Index2dC & end): Start line again.
bool IsElm() const: Still in line.
operator bool() const: At a pixel in line ?
bool Next(): Goto next point on line.
void operator ++(int): Goto next point on line.
Index2dC Data() const: Access position.
