Better printed crossword?

[VikR345]

Thanks for this excellent program.

Currently, the boxes that are printed in pdf/png are all individual boxes, inside their own grid. this makes some lines appear thick, if there is a box next to it, and some of them thin. Can we mark the boundaries as standard, and if required overwrite the lines between boxes, so as to give a more beautiful look to the output crossword.

For example, in calculate.py, draw_img, if we change to the following, the png generated is much more print friendly.
context.set_line_width(3.0) context.set_source_rgb(0.3, 0.3, 0.3)

Thanks.
