While running code analysis tools this issue popped up. As it is written it is
clearly a NOP, but the reason for why it is written that way remains unknown.
I suspect that it was a textfragment introduced by some repeat-function of the
used editor (think '.' in VIM). The code was introduced by commit a932a7a801
and looked like this in the original form:
if(!XQueryTree(FbTk::App::instance()->display(), window().window(),
&root_return, &parent_return,
&children_return, &nchildren_return))
parent_return=parent_return;//return;
Look at the outcommented return statement. I decided to return from that
function instead of the NOP.
WindowMenuAccessor returned strange alpha values if compiled
with 'g++ -Os'; unholy black magic happens if template<int> faces
functions returning only 'usigned char'.
