With 16 and 32 bit images, Image>Stacks>Make Montage always draws white
borders and labels and fills unused areas with black. With 8 bit and
RGB images, it draws in white and fills with black if the median pixel
value of the first slice is less than 200, otherwise it draws in black
and fills with white. With ImageJ 1.35m and later, there is an option
to draw in the foreground color and fill with the background color.
