This question regards centering of tikz picture in geometry layout. The question combines two answers that were answered here in tex.stackexchange.
The first answer explains how to position the tikz picture on the center of the page. But it does not give correct result, at least in this case.
The second answer creates in the loop tikz picture. But it counts the most important coordinates from guessed values (page cs:-0.5045,0.595).
So as a result the tikz picture is not centered and when printed both side, the difference is visible.
The question is: how to center horizontally and vertically the whole tikz picture in the geometry layout area? I can't figure out how to count the coordinates.

\begin{textblock}inside the\begin{inctext}environment? This MWE really works, it is a correct answer. But in my actual project it is still not centered - 1 mm difference is still too much, I guess. – chejnik Mar 03 '16 at 13:04textblockis a problem, because it is for absolute positioning and will quite likely not work well withinctext.inctextputs the content into a box and positions this box in the page center. – Thomas F.
