Then it would be still slow, but at least usable. The current 
"native" version is completly unusable. CVS is not working at all for 
me but one of the last point release was, and run faster, despite 
outputing via X11. The reason of this might be the double buffereing 
OS X performs.

We are not really doing anything fancy in windowed mode of SDL at the 
moment, really. a simple NSQuickDrawView, that is all. We plan to 
improve this in the future, when we have time.

Direct screen output is a bit tricky when in windowed mode, to say 
the least. You essentially can only do it properly if no window is 
covering your, and that include drop shadows from other windows. Of 
course, this is not so surprising, but ne has to do some hacking to 
determine whether this is the case or not etc.

There was an article on this somewhere (or maybe I read on a mailing 
list), if I can find it I'll make sure to let you know.
