## For each neighbor in structuring element, return the relative position and height.
##
## If P is the number of neighbors in SE, @var{offsets} are relative position
## from the center of the structuring element to them, of which heights are
## stored in corresponding columns of the array @var{heights}.
## @var{offsets} is an array with P rows and 2 columns, the first for the row
## offset, the second for the column offset.
