	SWT 0.38:
	I want to create a custom cursor from a three color .gif image: black & white & transparency.
	I have to use this wad to get the desired appearance:

	private static Cursor loadCursor(Display display, String name, int hotx, int hoty) {
		InputStream is= PartDragger.class.getResourceAsStream("icons/" + name + ".gif");
		
		ImageData data= new ImageData(is);
		RGB[] rgbs= data.getRGBs();
		int tp= data.transparentPixel;
		
		PaletteData palette= new PaletteData(new RGB[] { new RGB(0, 0, 0), new RGB(255, 255, 255)});
		ImageData image= new ImageData(data.width, data.height, 1, palette);
				
		for (int y= 0; y < image.height; y++) {
			for (int x= 0; x < image.width; x++) {
				int value= data.getPixel(x, y);
				if (value == tp) {
					image.setPixel(x, y, 1);
				} else {
					RGB c= rgbs[value];
					if (c.red == 0)			// invert black & white
						image.setPixel(x, y, 1);
					else
						image.setPixel(x, y, 0);
				}			
			}
		}
		
		return new Cursor(display, image, data.getTransparencyMask(), hotx, hoty);
	}

	Why do I have to invert the colors in order to get the expected result?
	Why do I have to use white in the transparent areas? In Images I have to use black!

	In addition the black parts of the cursor are xor-ed with the background.
	Builtin cursors don't have this behavior!
