// Some miscellaneous notes
//
// Reimplemented scrollbar metric and drawing routines from KStyle to allow
// better placement of subcontrols. This is because the subcontrols slightly
// overlap to share part of their border.
//
// Menu and toolbars are painted with the background color by default. This
// differs from the Qt default of giving them PaletteButton backgrounds.
// Menubars have normal gradients, toolbars have reverse.
//
// Some toolbars are not part of a QMainWindows, such as in a KDE file dialog.
// In these cases we treat the toolbar as "floating" and paint it flat.
