Printing of overhangs

[espr14]

v2.1.1 win64

This could look like something similar to previous issues but it brings new ideas.

Printing of overhangs was very often impossible without support. But it can be printed without any support. The print has to be just slowed down to few mm/s !!!

What's needed in slicer:

1. input for print speed of overhangs (bridge can be printed faster)
2. input for overhang flow ratio
3. overlap of paths (optional)

Paths of printing overhangs could be closer to each other due to lower flow ratio or to overlap paths a little bit (they melt together).

This is the 2nd attempt for overhang without any support. Printed with natural PLA, 1 mm nozzle and 1 mm/s print speed. For smaller nozzles and better cooling the speed can be increased. Still, you spare time by not building the support structure. The higher the overhang is, the more time you spare. And you spare filament as well.
