ipestyle.h
namespace ipe
[+] class StyleSheet (1)

	Change	Effect
1	Size of this class has been increased from 296 bytes to 328 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Virtual method CanvasObserver::canvasObserverSizeChanged ( ) has been added to this class.	The layout of v-table has been changed. This leaf class has no exported constructors and therefore applications will copy an old v-table of the class that will not contain a pointer to added virtual method. Call of any method in this class may result in crash or incorrect behavior of applications. NOTE: if new virtual method is called only from other new methods, then binary compatibility should not be affected.

Offset	Virtual Table (Old) - 6 entries	Virtual Table (New) - 7 entries
0	(int (*)(...))0	(int (*)(...))0
4	(int (*)(...))(& typeinfo)	(int (*)(...))(& typeinfo)
8	CanvasObserver::canvasObserverWheelMoved	CanvasObserver::canvasObserverWheelMoved
12	CanvasObserver::canvasObserverMouseAction	CanvasObserver::canvasObserverMouseAction
16	CanvasObserver::canvasObserverPositionChanged	CanvasObserver::canvasObserverPositionChanged
20	CanvasObserver::canvasObserverToolChanged	CanvasObserver::canvasObserverToolChanged
24		CanvasObserver::canvasObserverSizeChanged

Problems with Data Types, Low Severity (1)

ipestyle.h
namespace ipe
[+] class StyleSheet (1)

	Change	Effect
1	Field iTextPadding has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
