Slic3r: Feature request: Draft shield support

[alexxy]

It will be cool to have feature like a 'Draft shield' in cura. (currently its possible to set skirt height to needed value, but if it can be done in a automatic way...). This feature allow to print large objects in ABS without thermocamera...

So what you want is the ability to specify "skirt height equal to object height"?

[alexxy]

Right. I can do it manualy. But automatic way may be bettter =)

[lordofhyphens]

Set the skirt height to -1. Not very intuitive, unfortunately. I'll look into implementing this as a UI checkbox.

Not only that. A good warp shield / draft shield follows the vertical outline of the object closely (without the steep angles, of course). A good algorithm for generating that is described here: https://hal.inria.fr/hal-01141706/ (it is the algorithm used in the IceSL slicer).
