Sorry, I mean the whole MAP can never be shown.  In non-iso view with a 
non-iso map, if you have a wrapping map 80 tiles wide no more than 78 of 
those tiles can ever be shown.  You might wonder why this is; if all 80 
tiles are shown there should be no problem.  The problem is that if all 
80 tiles are shown there is a half-tile on the left and a half-tile on 
the right.  These are two halves of the same tile but only one of them 
gets drawn.  In my tests this happened when the with was 79 tiles as well.

In iso-view or hex the problem is worse.  Something like 4 tiles missing 
from each side.

And if the view and map don't match the problem is MUCH worse.  You can 
only ever show 50% of the map in any direction that wraps (so if it 
wraps in both directions, only 25% is ever visible).
