THE SYSTEM COLOR DROPPER

This sample demonstrates how to implement a Control Panel Extension.
The System Color Dropper is used to set your system colors.  To use,
simply place the coolcolr.cpl file in your WINDOWS\SYSTEM directory.
Run Control Panel and note the addition of the System Color Dropper
icon.  Run this app and drag and drop your favorite color to a menu
or scrollbar or any other system area.  The color will be immediately
updated.

This sample uses a modified version of the ChooseColor common dialog.
A custom template and hook function are used.
