Unfortunately if you want to create an Image from a DIBitmap object
you must violate the Alpha portability rules and refer to your
"item.parent", as in:
im = item.parent.createImage(myBitMap);
Then in your paint routine, do:
void paint(Graphics g) {
...
g.drawImage(im, x, y);
...
}
This will improve in Beta, but there may be some break in compatibility
in these interfaces (referring to your Applet's DisplayItem is a definate
no-no, but the only way to create Images from DIBitmaps calculated on
the fly by your Applet in Alpha unfortunately).
