[SDL] Where SDL goes in your game

[matt]

i have only written one app that uses sdl.   in that i keep the core
code separate from sdl.  perhaps think about how would it be ported to
another system.  the less dependent sdl calls or system specific calls
there are the easier it is to port.   not that you would port from sdl
to something else but hopefully explains the organization.
