This, I hope, fixes the display of centered figures so that the images are square in the middle of the page and the legend is correctly aligned with it.
There are also some minor tweaks to the legend text: it's justified, as per request. And I thought it may look better if we make it a tad bit smaller than regular text, because this is something I seem to remember seeing in books and papers. I have also made the background darker. If you are unhappy with it, please save everyone some time and pick a color you like then send me the html code for it.
