Comment (by annakrat):

 Thank you, I committed it in r68699. I did some minor changes in
 guisections and fixed one warning (-Wreturn-type). I have two more
 suggestions:
 * if you use different font than the default one, the background box is
 larger than it should be. You don't use `D_get_text_box` there, I wonder
 if this would give you better estimate?
 * The ticks are currently rendered in the same color as text, but they
 should be black as the legend outline.
