# This program draws three rows of circles on a tall thin
# panel with a grey background. The rows are perfectly horizontal.
# Each circle is 20 wide and tall and placed directly after the circle
# before it with no gap. The first row is in the top left of the panel
# in yellow and contains 5 circles. The middle row is about halfway down the
# panel a little to the right of the left edge and contains 10 in blue.
# The last is towards the bottom, on the right side, 8 long and light red.
