* Added a Desktop::BroadcastToAllWindows() method that sends all ServerWindows

Browse Source 
a message.
* The DesktopSettings class is now using that to send the new
  AS_SYSTEM_FONT_CHANGED message to all windows.
* The ServerWindow now propagates font changes to its decorator, causing it
  to update its drawing. That means changing the bold font in the "Fonts"
  preferences application will instantly change all window titles.
* Factored out a _RebuildAndRedrawAfterWindowChange() out of several Desktop
  methods, simplifying some code.
* The DefaultDecorator no longer calls _DoLayout() twice (through SetLook()),
  but instead calls the new _UpdateFont() method now also called by
  FontsChanged(), and SetLook().
* BWindow::GetDecoratorSettings() now also includes "tab frame" BRect with the
  exact footprint of the tab, allowing apps to know the size of the tab to
  position itself accordingly.
* Automatic white space cleanup.
