Which, for hexagon h give:
b c d l m n (instead of c d i m g b )

In hexmap with straight columns (opposed to straigth rows), you ALWAYS
take a [x,y-1] and [x,y+1], [x-1,y],[x+1,y]. And two more from either
y+1 or y-1  x-1/x+1 sides.

BTW, if somebody will start to implement this in C code, please use
hexes with aligned rows. It helps during repaint when you have
3d-looking sprites - you have to repaint only two hexes each from up and
bottom, instead of 3.
