@coz-eduardo-hernandez @ice0 what do you think about this: https://github.com/rodolforg/synfig/commit/d78e4f51d29adc634751b71fda97b131d97a24e7 ?

@yoSachinkr what about a tool for linking?

@Afterdie maybe you can be inspired by `synfig::waypoint_collect()`, available in `synfig/timepointcollect.h`, and adapt to this feature request. It retrieves all waypoints of a layer or canvas at a given time.

I can't reproduce the error present in Synfig CI / Ubuntu 20.04 Focal (Autotools) on my Debian OS, so I can't check what failed. :(

OK. I download the ISO image of Ubuntu 20.04, installed via Boxes in a virtual machine (minimal installation), installed git, cloned the repo, switched to this PR code, ran `./1-setup-linux-native.sh`,...

I repushed commits one-by-one and the problem is really the last one. Next I'll comment-out stuff to check where it fails, as I can't reproduce the issue locally.

> I will try to reproduce it. Thank you. The last commits I tried to find out the culprit test, but it seems to be more than one. The first...

@ice0 my next steps here are ~add/change docs~, move to synfig-core folder, change the template for that used in synfig-core. Could you take a look/review before I add those commits?...

@ice0 could you please take a look before I move ETL/_handle.h file to synfig-core folder (and then finish this PR)?
