[Xcb] Double buffering ...

[Lars Segerlund]

 Hi,

 I am just qurious , I have some programs using double buffering, and
they all seem to have stopped working in later X11 releases .. is the
double buffer support broken ?

 Double buffering is the only way I have found to do smooth updates on
old ISA hardware .... which I have in some systems.

 Any idea on an alternative path to double buffering ? If it's going
deprecated I would like to rewrite in a compliant manner.

 / best regards, Lars Segerlund.
