The updates never stop! I've added two new configuration options: bar_radius and invert.
The bar_radius option controls the border radius (i.e. rounding of corners) of the bars. But if you configured your progress bar to shrink with time, you'll see this:
That's no good! So I've added another option invert, which is meant to replace the hacky adjustment of bar_foreground, bar_background, and bar_direction needed to invert the bar colors. Now, adding invert: true will achieve the same thing, and it will work corrrectly with bar_radius!
