Comments:
Uses a version of the midpoint algorithm to iterate all grid points on a line between two positions.

Variables:
int dx;

int dy;

int d;

int incrE;

int incrNE;

int x;

int y;

int xe;

int ye;

int xc;

int yc;

bool isElm;

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.

Index2dC operator *() const
Access position.
