	I am finishing the View display code for the current project I am working
on and wanted to make it work on PAL Amigas, along with the US models.  What I
first decided to do was check the GfxBase->DisplayFlags and see if it's a PAL
screen, changing where the View positions itself. ( If it is a PAL display, it
starts the screen at line 28 and ends it at line 228 to center it. )  This is
done through the View->DyOffset.

	What I was wondering about is what the proper procedure was for making
a screen on a PAL display that needs to be 320 by 200 lines.  The main program
takes over the display when running, but can be paused to return it to any other
programs running in the background.  I have my own drawing procedures and layout
that need a 200 line display.  What do PAL screens look like when a 200 line
screen is opened up?  Is it just a background color to the bottom of the extra
56 lines?  What do other US/PAL programs do that do not open Windows on the
Workbench screen?
