Dark/High-Contrast Modes

RATS adapts all windows but graphs to the use of dark mode (Macintosh/UNIX) or high-contrast modes (Windows). The background color is typically a very dark gray, while the standard foreground is white. The highlights and various colorized texts are chosen to provide good readability vs the background while also being clearly different from each other and from the foreground.

Graphs are still done on a white background with the colors requested using the graph styles.

Note that Windows also has a separately selected "dark mode", but that is only partially supported. The main windows will have reversed colors, but dialog boxes are still light gray backgrounds. By contrast, the "high-contrast" modes redefine all the interface colors.
