# There are 4 different types of patterns used when generating a digit that is
# to be placed in a rectangle 3X5 pixels. Combinations of these are used to
# create a number pattern such as:
# * * *
# *
# * * *
# * *
# * * *
#
# 1) * * * Full Row
# 2) * * Both Sides
# 3) * Right Side
# 4) * Left Side
