This procedure retrieves the current GIMP foreground color. The foreground
color is used in a variety of tools such as paint tools, blending, and bucket
fill.

This procedure retrieves the current GIMP background color. The background
color is used in a variety of tools such as blending, erasing (with non-alpha
images), and image filling.

This procedure sets the current GIMP foreground color. After this is set,

will use the new value.
