If a background image has been set using
vte_terminal_set_background_image(),
vte_terminal_set_background_image_file(), or
vte_terminal_set_background_transparent(), and the saturation value is less
than 1.0, the terminal will adjust the colors of the image before drawing
the image. To do so, the terminal will create a copy of the background
image (or snapshot of the root window) and modify its pixel values.
