# This demo allows testing multiple combination of specific font variations.
# Two lines will be printed for every entry in "variations[]",
# First line showing the entry index and parametes,
# Second line being "Hello World".
#
# Example:
# If a printed line shows:
#   variations[2] =
#   Hello World
#   F=b B U AL=R
# It is the 3rd entry (zero-based index 2),
# with Font="B", Bold, Underline, Align=right.
