I propably made wrong question, i don`t want to burn my gfx card, but i
want learn about the rules which i have to obey when i using SDL.
For example when i am using ASCII i know why bits have that value and
how i can effectivly change it. When i initliaize a surface i don`t know
much more than what function i can use on this surface.
