Use a pixbuf to set the drag icon, combine code to create drag icons

Browse Source 
Mon Oct  7 16:28:11 2002  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkcolorsel.c (palette_drag_begin): Use
        a pixbuf to set the drag icon, combine code
        to create drag icons (Fixes #80092, #80093)

        * gtk/gtkcolorsel.c (get_screen_color): Don't warn
        on failure to grab keyboard/mouse. (#80085)

        * gtk/gtkcolorsel.c (palette_press): Return FALSE,
        so DND initiation is possible.

        * gtk/gtkcolorsel.c (palette_release): Set the color
        from the palette on release, not press.

        * tests/testgtk.c (create_color_selection): Use
        gtk_widget_show_all()
