Heyo,

(First: dont assume that i understand anything about the vp/vo layer
at all. This here is just a random blurb)

Imho this can be easily solved on x11's side by allocating some
buffers (X11images) before hand and manage them with get/release_buffer.
Every X11 programming book tells you anyways to allocate everything
you need at the beginning of your programm to allow caching at the
server side.

Also, as i already said on irc, we should IMHO integrate the
vo api into the vp and drop it. It would get us one api less
to document/learn and also remove some duplicated work as
a vo modules is much like a vf w/o an output.
