Explicitely draw an opaque rectangle using the background color rather
2003-01-30 Daniel Elstner <daniel.elstner@gmx.net>
* gtk/gtkcolorsel.c (palette_paint): Explicitely draw an opaque
rectangle using the background color rather than relying on
gdk_window_clear_area(), so that the palette works properly with
pixmap themes.
* demos/gtk-demo/colorsel.c: Install an "expose_event" handler
to fill the drawing area in the background color.
