Extrude mode mouse-move tolerance

[akks]

If extruder mode is active and user drags the edge a little (<10 px), no changes are made.
This hardens a "precise" mapping, so I was asked to add an advanced parameter and maybe reduce default to 5 px.

I'll commit advanced parameter with default 10px. 5 px and maybe other enhancements are to be discussed before closing the ticket.

In 7009/josm:

see #9952: added parameter extrude.initial-move-threshold (to tune ignoring small movements in extrude mode)

[skyper]

I always have to zoom to get it right. Why is there any threshold ? Would prefere none or 1 px.

[akks]

Sometimes it is done accidentally while double-clicking and it is hard to notice. It also depends on screen resolution.
Maybe 3 or 5 px ?

Replying to akks:

Sometimes it is done accidentally while double-clicking and it is hard to notice.

This is the same with moving less than 20 objects and I do not think it makes much damage if any.

It also depends on screen resolution.
Maybe 3 or 5 px ?

Fine with me, as long as I can set it to less manually through preferences.

Since extrude isn't the standard mode when using JOSM, and therefore accidental changes are presumably rare, I'd vote for setting extrude.initial-move-threshold to 0

In 7180/josm:

fix #9952 - set extrude.initial-move-threshold to 1px as default

[akks]

Thank you. The decision was to hard for me near tested release :)

I hope it satisfies everyone :)
