Description Sven Gothel 2013-10-12 18:33:15 CEST

If we have zero columns or rows, beginTile() will cause a division by zero exception.

EOT = end of tile-rendering

Refine eot() spec to allow caller to detect EOT properly.
beginTile() shall throw an IllegalStateException.

beginTile() caller shall issue reset() if eot() is reached 
to be able to perform tile-rendering again - if so desired.
