[pgf-tikz] circuitikz alignment

[Hartmut Henkel]

Hello,

in the pdfLaTeX snipplet below the line from point A to the inverting
input stub of the op-amp has a slight inclination. The line width is 0.4
pt (maybe bp), and from point A the line goes down by 0.3 pt until
reaching the stub (checked in inkscape after pdf2svg). In a larger
circuit this is well perceptible.

Increasing the PDF resolution does not help. It looks as if it can be
"corrected" by tweaking tripoles/op amp/input height/.initial, see the
commented lines below (which is not a solution).

Is this an issue (rounding?), which can be fixed?

Best Regards, Hartmut
