Image type SWT.ICON loses its type during re-scale

Image initialized as SWT.ICON in
org.eclipse.swt.graphics.Image.Image(Device, ImageData, ImageData) loses
its "Icon" properties i.e. type, mask etc. when handle for different
zoom level is requested. Now implementing correct init method when the
handle is requested for image type ICON.
