A side comment: It would be nice if in the long run (over the next
year or two) glob2 moved toward allowing maps whose dimensions are not
powers of 2. A 256 by 256 map is a bit small and boring, but 512 by
512 maps are way too big.
I think this is only, because this way we address the map faster.
With "|", "&", "<<" and ">>" we can quickly transform (x,y)
coordinates to the memory
address and back.
Nuage mentioned that accessing memory is by far more time consuming
than computing
the address. So probably "+", "%", "/", "*" are fast enough, and
arbitrary rectangle maps
possible.
