comment TikZ custom “to path” with curved edges
@Ignasi it isn't documented, I am simply exploiting the fact that in normal circumstances @ is a legitimate character in a node name, and tend to use such names for "throw away" coordinates that aren't required outside of the path drawing. The technical reason is that macros which have node names defined and called surrounded with \csname and \endcsname. In these cases it doesn't matter whether @ is a letter category code or other.

@Mike I just copied and pasted the code in the answer into a fresh file and it complied fine. So I am not sure why this happens for you.

comment How to fill a region between two curves in Tikz?
How about something like \shade [left color=gray!50, right color=white] (O2) to [bend left=8] (q3) to [bend left=8] (q2) to [bend right=8] (O2); ?

comment How to draw a Curvilinear system in Tikz/PStricks?
@Meshal arrows.meta came along with PGF 3.0. I guess you have the previous version. You can either upgrade PGF to the latest version, or simply use the old arrows stuff: change to \usetikzlibrary{arrows} and then remove the >=Triangle, */.tip=Circle, and replace it with >=latex,

comment How to draw a Curvilinear system in Tikz/PStricks?
@percusse exactly my thoughts while reading the OP's question. Unfortunately nonlinear transformations start off with low-level 2d coordinates, which wont help in this case (or at least I don't see a way it which it can).

revised Is there a triangular protractor shape built-in to TikZ?
Optimised code for speed and space, making it impenetrable and really hard to read.
