Let's suppose my Desktop Settings' color depth is High Color (24-bit). In
my applet I load a gif picture and store it as an Image object. Then I use
a PixelGrabber to fetch pixels from the picture. In result I get pixels with
color values with 5-6-5 bits for R-G-B chanels.

My question is:
How to get exact pixel values with 8-8-8 bits for R-G-B?
I'd like my applet to be Desktop Settings independent, which I mean to get
always real color values for the pixels, no matter what color depth is set
by user on his desktop.
