Creates a transformation of the source image this by scaling by
then translating by
offset_y, then renders the rectangle (
dest_height) of the resulting image onto the destination image replacing the previous contents.
If the source rectangle overlaps the destination rectangle on the same pixbuf, it will be overwritten during the scaling which results in rendering artifacts.
the Pixbuf into which to render the results
the left coordinate for region to render
the top coordinate for region to render
the width of the region to render
the height of the region to render
the offset in the X direction (currently rounded to an integer)
the offset in the Y direction (currently rounded to an integer)
the scale factor in the X direction
the scale factor in the Y direction
the interpolation type for the transformation.
