// version : 1.4
// Gradient Animation added
// version : 1.3
// Separated to window independent classes CProgress and CGradient (base)
// Added palette support for 256 colors mode (to CGradient)
// Added shaped style drawing 
// Old history of CProgressCtrlX:
// version : 1.2
// Added support for "Any angle text rotation" 
//   (define PBT_ANY_ANGLE and set font with appropriated angle)
// Added text alignment
// Added possibility to format text (via virtual function FormatText())
//   e.g. you can show percent as decimal fraction instead of integer
// version : 1.1
// Added multi-color gradient
// Added filling with brush for background and bar(overrides color settings)
// Added borders attribute
// Added vertical text support
// Added snake mode
// Added reverse mode
// Added dual color for text
