If a color is not within the indexed image's palette, we can consider it
to be out-of-gamut too (the gamut of such image being its palette).
This is a first step towards fixing #2938. Basically currently opening
indexed images is not made obvious and you can end up thinking GIMP is
broken as when you try to paint with a given FG or BG color, you may get
a completely different color on the canvas. And it is not obvious to
realize why. Now at least, the FG/BG color will tell you when the color
you are trying to paint with is not within the accepted palette.

...via hover tooltips
Use the GtkWidget::query_tooltip() signal on GimpFgBgEditor to emit an
own signal "tooltip" that has the hovered widget area as parameter.
Connect to GimpFgBgEditor::tooltip() in gimptoolbox-color-area.c and
set separate tooltips on the widget's areas, including the shortcuts
for "Swap colors" and "Default colors".

* app/widgets/gimpfgbgeditor.[ch]: use the coordinates passed in
the color drop callback instead of remembering them in the
drag_motion handler.

* app/widgets/gimpfgbgarea.[ch]: implement GtkWidget::drag_motion()
and set the FG/BG depending on where the color was dropped. Also
set the drag status accordingly so the cursor indicates whether
dropping will have an effect or not. Fixes bug #145219.
2004-05-27 Michael Natterer <mitch@gimp.org>
* app/widgets/widgets-enums.[ch]: added enum GimpActiveColor which
can be one of { FOREGROUND, BACKGROUND },
* app/widgets/Makefile.am
* app/widgets/gimpfgbgeditor.[ch]: new widget implementing the
FG/BG/Swap/Default color area known from the toolbox.
* app/widgets/gimptoolbox-color-area.c: use the new widget.
* app/widgets/gimpcoloreditor.[ch]: replaced the FG/BG buttons and
the color area by a GimpFgBgEditor.
