I've had luck in the past by doing my annotations in two stages.
First I plot them with *THICK=3, COLOR=0, and then a second time with
*THICK=1, COLOR=255. The result is a white tickmark (or plot symbol)
within a black outline. This kind of thing is visible no matter what
the background color is. Of course, you can reverse the colors, the
point is to plot with two different colors and thicknesses.
