// CStatusBar derived control to add auto-fit, tooltips and command handling
//
// You are free to use or modify this code, with no restrictions, other than
// you continue to acknowledge me as the original author in this source code,
// or any code derived from it.
//
// If you use this code, or use it as a base for your own code, it would be 
// nice to hear from you simply so I know it's not been a waste of time!

// Version History:
//
// Version 3.1 - 24 Jun 2004
// =========================
// - Updated to support Unicode builds
// - fixed bugs:
//   - using ON_COMMAND macros causes assertion failure
//   - updating tip text re-adds the tool, and causes old one to overlap
//   - crash in GetPaneCursorIndex() if no pane cursors set and also in
//     GetPaneFlagsIndex() if no pane flags set (reported by Tom Mason)
//
// Version 3.0 - 28 May 2003
// =========================
// - Can now specify a custom cursor for a pane
// - Added ability to specify a hand cursor to use instead of the default
//   (the default is only available on Windows 98/ME and Windows 2000/XP)
//
// Version 2.0 - 15 Apr 2003
// =========================
// - Extended control to allow pane tool-tips to be specified as part of the 
//   pane's text, separated by a new line ('\n') character.
// - Added ability to show multi-line tool-tips by including carriage returns 
//   ('\r') and/or line breaks ('\n') in the tip text.
// 
// Version 1.0 - 18 Feb 2003
// =========================
// Initial version
