D2TM on 800×600 part I

As told before I was pondering about 800×600. I just simply changed the values 640×480 into 800×600 and this is what the engine gave me:

Not bad, considering everything worked quite good except for a few (very) noticable things:

1. As predicted, the ui  is still 640×480
2. The credits are drawn properly , but looks weird due nr 1.
3. The minimap is drawn ok, but you cannot select where to go, you actually have to go to the very bottom right.
4. The map boundaries are not always respected; making the game crash sometimes.
