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.
