*******************************************************************//**
\class ControlToolBar
\brief A ToolBar that has the main Transport buttons.
In the GUI, this is referred to as "Transport Toolbar", as
it corresponds to commands in the Transport menu.
"Control Toolbar" is historic.
This class, which is a child of Toolbar, creates the
window containing the Transport (rewind/play/stop/record/ff)
buttons. The window can be embedded within a
normal project window, or within a ToolbarFrame that is
managed by a global ToolBarStub called
gControlToolBarStub.
All of the controls in this window were custom-written for
Audacity - they are not native controls on any platform -
however, it is intended that the images could be easily
replaced to allow "skinning" or just customization to
match the look and feel of each platform.
