originhex-radius `cell`procedureA list containing the world/screen coordinates of six points corresponding to the vertices of a hexagon at

`cell`with radius`hex-radius`.`origin`is the position, in world/screen coordinates, of the cell at row 0, column 0.`hex-radius`is the distance, in world/screen coordinates, between the center of a hexagon and any of its vertices (which is the same as the length of one hexagon side).No bounds wrap-around or checking is done. See

`horizontal-wrapper`,`vertical-wrapper`or`within-bounds?`for that.(Note: curried.)
