[pstricks] pst-geometrictools

[Antonis Tsolomitis]

Could I make a suggestion for the package for the future ?

In Euclidean Geometry all constructions are made with a ruler and a compass.
"Ruler" means a regular ruler but without any marks. So it would be
historically
correct for \psRuler to have an option to remove all measurements (the
hole can stay 😁)
Unless there is already such an option and did not find it.

In high schools another instrument is also used, the "gnomon". You can
see this tool held
by Pythagoras in the current statue at Samos Island:

<https://en.wikipedia.org/wiki/Pythagoreio#/media/File:Pythagoras_1.jpg>

The resolution is good enough to allow zoom on his left hand.

Typically gnomons have one angle 30 degrees and another 60 degrees so
they are different
than the triangular tool used in pst-geometrictools.

best,

Antonis.
