int QisLib_SetTransformation(CQisMetric Dx, CQisMetric Dy, int ReflectAxis, double
	Angle, double ScaleX, double ScaleY);

	Dx: Translate in X direction by 'Dx' vector units. (DBU or UU)
	Dy: Translate in Y direction by 'Dy' vector units. (DBU or UU)
	ReflectAxis: _QIST_N (no mirroring), _QIST_X (mirror about X axis), _QIST_Y (mirror
	about Y axis) or _QIST_XY (mirror about X,Y axes)
	Angle: Rotatation in degrees about Z in counter clockwise direction.
	ScaleX: Scale in X-direction.
	ScaleY: Scale in Y-direction.

	success: 0
	failure: one of the following values :

	-1: QisLib has not been initialized.
	-2: Internal memory error occurred while setting transformation.
	-3: The current cell set via QisLib_OpenStructure is invalid or does not exist.
	-4: File open in progress, operation not permitted.

	- QisLib_SetTransformation sets the transformation for the current cell
	(QisLib_OpenStructure). These transformation settings are applied to the data when
	they are drawn, output as vectors and saved to an output GDSII/OASIS file.
	- User can have a different transformation for every cell. Just call
	QisLib_OpenStructure and then call QisLib_SetTransformation.
	- User can set different transformation for each root cell, the root cell would be
	drawn using the transformation. When saving, the data in the root cell's first
	level would be transformed.
	- Transformation takes place in this order: dx, dy, xy mirror, rotate, scale x, scale y.
	- cell extents returned by QisLib_GetStructureExtents are transformed by the
	QisLib_SetTransformation settings on the queried cell.
	- Different scales can be specified for X and Y. This might be useful for drawing and
	Tiff extraction.
	- GDSII and OASIS output with hierarchy will not have the correct scale and rotation
	in the references because they don't support different XY scales. (QisLib_SaveGDSII,
	QisLib_SaveGDSIIStructure, QisLib_SaveOASIS and QisLib_SaveOASISStructure)
	- GDSII and OASIS output path width will not look the same as drawing because the
	width might look different along the x and y axis but there is only one width in
	the GDSII or OASIS output.
