Disallow high-quality (640x480) tilted screen if MAXYDIM is less than 640.

Browse source 
This fixes the crash on Wii when looking sidewards (e.g. when dying), but
makes the tilted view look more pixelated.
The problem was that an attempt was made to render onto a 640x640 tile for
the rotated view, but the base engine arrays were too small for that.
