New printer option fan_direction (undefine/left/right/both, default
undefine) declares which side the auxiliary part-cooling airflow comes
from. When set and the printer has an auxiliary fan, auto-orient adds a
yaw rotation so the dominant overhang area faces the airflow, and newly
added primitive shapes are pre-oriented the same way (except the Cube,
whose axis-aligned bounding box the pressure-advance pattern calibration
depends on).
- FanDirection enum + fan_direction printer option (Accessory group,
enabled only with auxiliary_fan)
- orient engine: weighted overhang areas per candidate, yaw-direction
search, vertical rotation applied on top of the primary orientation;
the cooling weights are taken from the candidate actually chosen,
including the flat-bottom tie-break
- orient_for_cooling() for primitive placement
- set fan_direction=left on H2C/H2D/H2D Pro/X1/X1E/P1S 0.4 profiles
(X1C/H2S/P2S/X2D/Qidi X-Max 4 already carried the key, which now
takes effect)
With fan_direction unset or no auxiliary fan the vertical rotation stays
identity and auto-orient results are unchanged; slicing and g-code are
never affected.
[STUDIO-1079] Large plane not stick to bed
[STUDIO-1437] Model auto flipping bug
1. Changed the orientation threshold so that some tiny rotations wont be ignored.
2. Added flipping detection. Rotation with same unprintability will not be excuted.
3. Added the weight of first layer area to improve large planar face orientatio performance while not influence other objects with small first layer areas.

The tolerance of orientation filter is too large.
