I've managed to add texture and lightning to
Allegro's example 25. And i increased the
size of the world.

I now have two problems:

Does anybody know, if there's a way to render
only the sqares, which are visible, and to get
them in back to front order ?
I think, transforming and projecting every square
and (what im planning) sorting them is not
necesarry, cause of the way they are stored.

And my second question: How large exactly
can i make world-coordinates, when using
floating points ? With fixed-point-integer
i could use -23000 to +23000, whats the
range with float ?

hope this questions dont sound too stupid
