// History
//
// 21 Mar 2002 1.00 First release
// 26 Mar 2002 1.01 Fixed DateTime-bug in cursor mode
// (thanks to Pavel Klocek for providing the fix)
// Fixed crash when adding trend or moving average
// 11 Apr 2002 1.02 Panning in cursor mode added
// Added support for very large and very small numbers
// Values greater/less 10E6/10E-6 are now automatically shown in
// exponential format
// Completely redesigned autoscaling (only for normal axes,
// DateTime types follow)
// Added data notation marks
// Added Get/Set member functions
// Added nth-order-polynomial trend
// 25. Sep 2002 1.03 Now compiles under VC7
// Load/Save for properties/data/object persistence
// Added zoom-history
// unreleased 1.04 Added UNICODE support
// Added background bitmaps
// Added bitmap objects
// Added gradient colorranges
// Added axismarkers
// 02.12.2004 1.05 Added support for WINDOWS CE (needs improvement)
// Logarithmic axes (thanks to ...)
// Added polygonfilling between 2 curves
// Several Bugs fixed by Joerg Blattner
// Added Cursor-Synchronisation
// Curve editing mode
// Measuring mode
//
//
// Known issues
//
// - clipping in print preview doesn't work
//
// Additional credits
//
// - Ishay Sivan (Bugfixing)
// - Pavel Klocek (Bugfixing)
// - James White (color button)
// - Chris Maunder (color popup)
// - Keith Rule (MemDC)
// - J.G. Hattingh (parts of Device Context Utilities)
// - J鰎g Blattner (Bugfixing, improvements)
