Of course, there are more undo/redo related methods in kis_doc.h; they coul=
d=20
perhaps all be abstracted away to this interface:


	void beginMacro(const QString& macroName);
	void endMacro();
	bool inMacro() const;
	void addCommand(KCommand *cmd);
	Q_INT32 undoLimit() const;
	void setUndoLimit(Q_INT32 limit);
	Q_INT32 redoLimit() const;
	void setRedoLimit(Q_INT32 limit);
	void setUndo(bool undo);
	bool undo() const;

Not sure what the macro methods do, though.

I'm still working at the endianness bug. A very educating experience -- jus=
t=20
swapping the values of the PIXEL_RED etc. defs doesn't do it :-).
