Jeff Teunissen 17ea696c0d One of the biggest things keeping -mem/-heapsize numbers up is the video
memory in software mode. This is now taken care of, the memory is now
grabbed using calloc.

On Unix systems and all systems using SDL, the default video memory is now
8MB. This should now be enough for almost everybody, unless you have some
truly huge maps and boatloads of sounds. The minimum memory allowable is
now down to 4MB, but complex maps and/or models can cause the game to quit
-- not like this wasn't a problem already with the old 5.3MB lower limit,
but there it is.
