>	class XMatrix

	Author:		Mario_Shamtani (Xara Group Ltd) <camelotdev@xara.com>
	Created:	13/5/1993
	Purpose:	Represents a mathematical transformation matrix containing 64-bit values.
				Use instead of Matrix when larger co-ordinates are needed. Based on the
				1.11 build of matrix.h and the 1.5 build of matrix.cpp.
	Errors:		None.
