graphic properties
Every draw function hands back a graphic object. Change these properties to move it, fade it or hide it.
When you are finished with a graphic, remove it with destroy(box). The same destroy() works on
objects and text too.
| box.x = 100 | sets the x position to 100 |
| box.y = 100 | sets the y position to 100 |
| box.z = 1000 | draws it in front of anything with a lower z |
| box.angle = 45 | turns it 45 degrees |
| box.alpha = 0.5 | makes it half see-through |
| box.visible = False | hides it without destroying it |
| box.scaleX = 2 | sets the width to 200% |
| box.scaleY = 2 | sets the height to 200% |
