That sounds fair enough, however many programmers don't use the fbcon mode
resolution or the safe default resolution.  A program that runs under DOS,
MS Windows and Linux X may need to start up in full screen mode on one
platform and as a 100 x 100 window on another computer.  The full screen
mode resolution and color depth could be randomly changed by the user.  I
use a screen res of 640x480 in DOS, 800x600 in MSW and 1024x768 in Linux.
But the allegro program I am writing starts up using GFX_SAFE to make the
program appear on top and in focus, then changes to 600x350 window size.
The last thing I need is my program filling the whole screen and somehow
locking the user out of the desktop.  And what if the user changes the
color depth, making all of the colors change at random?
