This theme inverts the colors in the theme_gray, a
white panel and a light gray area around it. This keeps a white
background for the color scales like theme_bw. But
by using a gray background, the plot is closer to the
typographical color of the document, which is the motivation for
using a gray panel in theme_gray. This is
similar to the style of plots in Stata and Tableau.
