'GI.Gtk.Interfaces.ColorChooser.ColorChooser' is an interface that is implemented by widgets
for choosing colors. Depending on the situation, colors may be
allowed to have alpha (translucency).

In GTK+, the main widgets that implement this interface are
'GI.Gtk.Objects.ColorChooserWidget.ColorChooserWidget', 'GI.Gtk.Objects.ColorChooserDialog.ColorChooserDialog' and 'GI.Gtk.Objects.ColorButton.ColorButton'.

{- | When ::use-alpha is 'True', colors may have alpha (translucency)
information. When it is 'False', the 'GI.Gdk.Structs.RGBA.RGBA' struct obtained
via the 'GI.Gtk.Interfaces.ColorChooser.ColorChooser':@/rgba/@ property will be forced to have
alpha == 1.

Implementations are expected to show alpha by rendering the color
over a non-uniform background (like a checkerboard pattern).

Adds a palette to the color chooser. If /@orientation@/ is horizontal,
the colors are grouped in rows, with /@colorsPerLine@/ colors
in each row. If /@horizontal@/ is 'False', the colors are grouped
in columns instead.

The default color palette of 'GI.Gtk.Objects.ColorChooserWidget.ColorChooserWidget' has
27 colors, organized in columns of 3 colors. The default gray
palette has 9 grays in a single row.

The layout of the color chooser widget works best when the
palettes have 9-10 columns.

Calling this function for the first time has the
side effect of removing the default color and gray palettes
from the color chooser.

If /@colors@/ is 'Nothing', removes all previously added palettes.
