# usage: run-in-mode.sh <mode> <port> <outdir> fixtures/t14/para_fill.py [<file.odt>]
# no file: writes <outdir>/para-fill-<mode>.odt with a solid fill in a paragraph style, a solid fill set directly on a paragraph
#         and a gradient fill set directly on a paragraph, in the office's current save mode.
# file:    loads that file and prints the fill properties of the style and of the three paragraphs.
