Ok, this would explain the slowdown on the Space Quest 3 opening, the 
opening starts as a small blue block and grows in size to cover the 
entire screen.
For FreeSCI this would mean just increasing the block by a few lines on 
each side, which is fast, for SDL this would mean copying a complete 
screen each time the 'block' grows.

You are right, X11 got very popular and had some released behind. I 
thought Xlib would be slower as SDL, are you saying it would be faster 
if we would use Xlib/XWindows for this?
