Detailed Description

I know this is confusing, but the original game had two different Globals arrays

Obviously, the user won't try to put them out in hyperspace, but may do this if he wants the box to be flush with a corner (to grow up, down, left, or right.) Figure B is the re-calculated coordinates of the boxes in order to get them onto the background. The new boxes should not be in the interface or in the letterboxed areas at the top and bottom.

If someone says to draw conversation box (a) at the location in Figure 1, then have it automatically re-position itself into where it is in Figure 2. The extra space around the newly re-positioned box should be about 10 pixels wide and/or tall. Make the spacing visually look identical. In other words, if the height of the border is 10 pixels, the width on the side of the new conversation box may need to be 15. You may have to experiment with this. In even other words, you should correct for the aspect ration.

The same thing should work for boxes (b), (c), and (d).
