The 'bmp display' command accepts optional X and Y values for the position
of the image to be displayed. Change the code which parses the command line
to accept negative values.
This feature is useful if you want to use a frame buffer for the console, and
you want a banner displayed on the top of the screen that never scrolls off.
This can be accomplished by declaring that the width and height of the video
screen is smaller than it really is, and then drawing an image in the
undeclared area.
For example, if you have 1280x1024 monitor, and you want to display a banner
on the top of the screen that's 100 pixels tall, then video_hw_init() should
say that display is really 1280x924, and then the banner should be drawn at
position (0, -100).
