Could I make a suggestion for the package for the future ?<br>
<br>
In Euclidean Geometry all constructions are made with a ruler and a
compass.<br>
"Ruler" means a regular ruler but without any marks. So it would be
historically<br>
correct for \psRuler to have an option to remove all measurements
(the hole can stay 😁)<br>
Unless there is already such an option and did not find it.<br>
<br>
In high schools another instrument is also used, the "gnomon". You
can see this tool held<br>
by Pythagoras in the current statue at Samos Island:<br>

<br>
The resolution is good enough to allow zoom on his left hand.<br>
<br>
Typically gnomons have one angle 30 degrees and another 60 degrees
so they are different<br>
than the triangular tool used in pst-geometrictools.<br>
