The Graphics2D.scale() works well for images, but not text.
e.g. I just put one button onto a panel1, with "abcd" on it, and of course the button has enough place to show the whole text. But when I scale another panel2 with some factor, and put the panel1's image onto the panel2's graphics, the text on the button is truncated, i.e. become "ab..."! That's unreasonable! If the orginal button can show the whole text, the button on the scaled image should also show the whole text.
