var() step/steps don't seem to work properly

[rlafuente]

e.g. being able to increment variables by specific amounts, or steps.

Sounds good [bikesheds] it should be called step

We should think about how something like var() could work in shoebot.next ... this nodebox var thing doesn't feel exactly right.

[rlafuente]

step/steps was implemented, right? I saw that briefly when documenting vars but didn't test

[stuaxo]

I can't test right now, but looks like both are supported

Briefly tested it on vars/cornu.bot and it's not working as expected. Will look further later

Seems like the default in Gtk when things get small is 0.1, you can tweak this by changing the number of digits on the adjustment (amount of decimal points the slider can show while adjusting).

I put in a slightly dumb fix, that says if the difference between min and max > 2 set_digits to 2.

It doesn't exactly get you to the right step but it's more usable.
