Purpose : This class encapsulates a toolbar that can be used with
"CRulerRichEditCtrl". The class is derived from "CToolBarCtrl",
and manages a formatting toolbar
Description : A "CToolBarCtrl"-derived class. Reads a toolbar resource
with the ID "TOOLBAR_CONTROL" and adds combo controls for
font name and -size, as well as a color picker at the
positions "FONT_NAME_POS", "FONT_SIZE_POS" and
"FONT_COLOR_POS" respectively.
Usage : Created by the rich edit mini-editor.
