# A slides file should populate the variable slides with
# a list of tuples. Each tuple should have:
#
# - Slide content
# - User data
# - Canvas width
# - Canvas height
#
# Slide content can be a string, a list of strings,
# a function returning one of those, or a generator
# yielding strings. The user data should be a dictionary or
# None, and is both used to communicate options to the
# renderer and to pass extra options to the theme functions.
#
# A function-based slide content will be passed a renderer object.
# Renderer is an object similar to a cairo.Context and
# pangocairo.CairoContext but has its own methods too.
# The more useful of them here are put_text, put_image, and
# set_allocation. See their pydocs.
