// widgetToolbar.c  -- Toolbar widget
//
// A horizontal container with a raised 1px bevel background, used to
// hold buttons, separators, spacers, and other control widgets in a
// strip at the top of a window. Like StatusBar, the toolbar is a
// standard HBox layout with custom paint -- child widgets position
// themselves via the generic horizontal box algorithm.
//
// The 1px raised bevel (vs the 2px used for window chrome) keeps the
// toolbar visually distinct but lightweight. The bevel's bottom shadow
// line serves as the separator between the toolbar and the content
// area below it.
//
// Tight 2px padding and spacing match the StatusBar for visual
// consistency between top and bottom chrome bars. Children (typically
// ImageButtons or small Buttons) handle their own mouse/key events.
