Call XdbeQueryExtension before of calling any Xdbe function
XdbeQueryExtension() tells to the caller if the Xdbe extension is present in
the X server, so it should be called for sanity. But like is said in
XdbeQueryExtension(3):
No other Xdbe functions may be called before this function. If a
client violates this rule, the effects of all subsequent Xdbe calls
that it makes are undefined.
it is mandatory call this function.
