1. Only draw infill in normal nodes of hybrid support.
Previously when hybrid support was selected, all nodes would have
infill including the circle nodes which don't need infill. Now we draw
infill only when there are normal nodes.
2. Move remove_bridge after small overhang removal because the trimmed
bridge may be detected as small overhangs.
3. Only split circle nodes in draw_circles to prevent floating circles.
4. Fix the issue where tree support infills may not be aligned,
which is caused by the changing spacing of filler.
5. Fix a bug where lightning infill in tree support may crash.
Note: it is still not prepared to set lightning infill as default,
as for some models the generation time of lightning infill is still
too long.

1. Fix sharp tail detection in normal support.
The not operator in front of overlaps was missing.
2. Fix bridge removal.
After adopting Prusa's smart bridge direction detection, the bridge
angle may be pi, so our previous method (comparing angle to 0 and pi/2)
was not right. Now we simply check if the bridge direction normal vector
is aligned to x-axis or y-axis.

1. improve sharp detection for small regions.
When the region is around 1 extrsion width, previous method may miss some sharp tails.
Now we reduce the width threshold to 0.1*extrusion_width for sharp
tails.

benchy.
2. improve is_support_necessary.

is_support_necessary 10 times faster.

3. for tree(auto), interface top layers=0, max bridge length=0, support_critical_regions_only=false (only in this way the bridge is fully supported)
Note:
Since now the surface type depends on more parameters, changing them will trigger re-slicing and making the whole process slower.

So tree supports won't go outside the bed.

clip the supports in a different way after moving, you need to change

2. clipping with the occlusion region is not complete, and an error
message of "outside toolpath" will still be popped because we use

This may cause tall objects be printed before short ones. There are two
possible solutions:
1. do strict ordering only when y-overlap is large enough (the one

Currently only works for tree supports, will need to copied to normal
