Detailed Description

TikZ/LaTeX geometric drawing utilities.

This module provides a PGF/TikZ backend to render geometry objects into a fixed-size plane. Its public API mirrors the EEPIC model (Eepic_Plane + put_in_plane) so existing workflows can migrate incrementally.

Typical usage:

Tikz_Plane plane(120, 80); // width/height in mm
put_in_plane(plane, Point(0, 0));
put_in_plane(plane, Segment(Point(0, 0), Point(10, 20)));
plane.draw(std::cout);

Robustness notes:

• Degenerate global ranges (all x equal or all y equal) are handled without division by zero.
• Empty planes are valid and produce an empty clipped tikzpicture.
