[Xcb] DBE help ...

 Hello again,

 I have mailed the list on this topic before, but now I have done some
testing and I am quite certain that xlib's BDE extension could be of
use in xcb.
 I have checked some of my old programs, and also alternative
techniques to do the same thing, ( allocating a big pixmap, and
scrolling it in the drawable area of the window ), but nothing really
gives the same performance as dbe & shm as for flickerfree animation.

 I am thinking that I could port xdbe to xcb, and my question is if I
have understood the process correctly.

 As I understand it I need to do the following points:

 1. port the xdbe proto header file.
 2. somwhere add the functions to make the calls , Xext ?

 Can I have a bit of help please, it was 5 years since I did any
'serious' X programming, and everything is changed :-D ( whine ...
whine whine ... and some more whining ... ).

 It looks like it's not to hard from glancing the other X extensions
.... but I known to be wrong on occasion .

 / regards, Lars Segerlund.
