I'll not touch it myself, maybe you or Axel can do that: I don't feel 
confident yet I don't oversee important details. OTOH I am very pleased 
with the simplicity of the whole API/portlink/app_server setup. I could 
very fast track down the errors I sought :-) My compliments!
Upto now I just point Axel (you guys) at what I find, and he (you) 
tell(s) me if I should fix it or if someone else should do it. Suits me 
OK at this time :)

BTW: It's become clear to me that Haiku uses (about) twice the CPU 
power compared to R5/dano for overlay video playback. Could it be that 
there's some bitmap duplication code somewhere?

Ah, OK. Well, pageflipper would be an interesting test then ;-)
Another thing I think I'll try: setting a virtual screen via 
BScreen::Setmode. I'm curious how well the app_server handles it ;-)
