////////////////////////////////////////////////////////////////////////////////
// Revision History		- by PJ Arends ([email protected])
// July 1, 2001			- added functionality to set font to parent windows font
// July 15, 2001		- added SetTextColor() and GetTextColor() functions
// August 2, 2001		- Added functionality where the control now responds to
//						  PBM_* progress bar messages. Now the control can be
//						  controlled by sending messages to its HWND.
//						- added PBM_SETTEXTCOLOR and PBM_SETSHOWTEXT messages
//						- added the ability to call GetPos() via OnGetPos()
// January 3, 2005		- By Kriz: Added two basic methods some other changes to
//						  allow the user to switch between the three alignment
//						  styles LEFT, CENTER and RIGHT - even on the fly if that's
//						  needed. Methods: AlignText and AlignTextInvalidate
//						- By C Maunder: updated the code so it compiles in VC7
// March 6, 2006		- By A. Bommarito: changed to allow text in vertical
//						  progress bars; added method to change text background
//						  color; added capability to independently control display
//						  of text and percentage complete; added marquee mode;
//						  changed to exclusively use messaging interface
// February 22, 2007	- By A. Bommarito: changed to fix problem where progress bar
//						  border didn't display on XP and above when a manifest file
//						  specified use of Version 6 of the Common Controls; fixed
//						  problem with AppendFormat method being used without an
//						  _T() around the format string - caused compile error when
//						  using Unicode (message from dev75040); added complete turn
//						  off of Marquee style (message from Robert Pickford)
