Some comments (that hopefully help to get an even better understanding
of the codebase):

* the gfx::setup(...) method could be used to create the cache and
read the initial cache size from configuration. It's called during
engine startup (see main/adonthell.cc).
Something like

   s_int32 cache_size = cfg.get_int ("Video", "CacheSize", DEFAULT_CACHE_SIZE);
   surfaces->setmaxmem (cache_size < 0 ? DEFAULT_CACHE_SIZE : cache_size);

would do the trick. Btw., the way you calculate the surface size seems
good to me.

* similarly, the gfx::cleanup() method could be used to free the cache.

* the animation class currently loads surfaces, but never releases them.

* we've defined system-independent int-types in base/types.h (that
still need to be properly initialized by the build system). Their use
is preferred, although as long as no serialization is involved,
there's no harm in not using them.

There are a couple cosmetic issues like mixture of tabs and spaces or
not having the cache class in a separate set of files (am I doing too
much Java at work? ;-)) and method names without underscores between
words, but none of that is a big deal. Since there is no real style
guide, none of that would have been obvious.


So, are there any other tasks you're interested in? Let us know and we
can either discuss stuff via adonthell-devel, IRC or IM.
