The only use of the infinite iterator is, as far as I know, the floodfill 
code, where it is used to fill an area with a pattern. The workings of it are 
very simple: it checks if it tries iterating over the boundaries of the 
underlying device, and resets the current position accordingly. 
 
If this infinite paint_device would act the same way, it could probably just 
use the same idea of resetting the position when accessing positions that are 
outside the 'real' image boundaries.
