This is great but now I have a new problem. How can I programatically
switch between legacy mode and new mode? What I mean is, when the screen is
in landscape 640 X 480 mode, I want to use the new resolution. When the
screen is in portrait mode, I want it to be in the 240 X 320 mode. We have
two different sets of bitmaps for each resolution mode and I can switch
between the two. When we are in portrait mode, I can't have the display at
480 X 640, I need it to be in 240 X 320.
