Last time I've seen it there weren't any generic "wrapper" class.
There was support only for calls with xcb_window_t* as first argument,
or something like this. This (with "no more Xlib" rule) stopped me
from working on my latest patch for KWin.

When I tried writing template-based wrapper, I came up with almost the
same code. However, I didn't like the result, and used raw xcb C api
with smart pointers (for replies) in my project.

Of course :)
At least, KWin isn't the only C++ project that uses xcb. Reinventing
these wrappers again and again in every project doesn't look good.
