# Stamps should be used when you have content that will be included multiple
# times in a document. Its advantages over creating the content anew each time
# are:
# 1. Faster document creation
# 2. Smaller final document
# 3. Faster display on subsequent displays of the repeated
# element because the viewer application can cache the rendered
# results
#
# The create_stamp
method does just what it says. Pass it a block
# with the content that should be generated and the stamp will be created.
#
# There are two methods to render the stamp on a page stamp
and
# stamp_at
. The first will render the stamp as is while the
# second accepts a point to serve as an offset to the stamp content.
