""" Generates a pseudo ancillary data for blocks that depend of
what are surrounded and don't have ancillary data
This uses a binary number of 4 digits to encode the info.
The encode is:
Bit: 1 2 3 4
Side: x y -x -y
Values: bit = 0 -> The corresponding side block has different blockid
bit = 1 -> The corresponding side block has same blockid
Example: if the bit1 is 1 that means that there is a block with
blockid in the side of the +x direction.
You can rotate the pseudo data multiplying by 2 and
if it is > 15 subtracting 15 and adding 1. (moving bits
in the left direction is like rotate 90 degree in anticlockwise
direction). In this way can be used for maps with other
north orientation.
North position can have the values 0, 1, 2, 3, corresponding to
north in bottom-left, bottom-right, top-right and top-left of
the screen.
The rotation feature is not used anywhere yet.
