Improves generation of images with railings / balcony, and provides against "railing" ??? pose.

Keywords:

1. balcony-in - should prioritize looking in at the balcony.

2. balcony-out - should prioritize looking out from the balcony.

3. balcony-above - should prioritize looking down at the balcony. ( pov is helpful for ??? scenes )

4. balcony-below - very weakly trained, looking up ( as in under the railing ) it tends to just be a lower angles in practice.

Adding "???" to any of these will shift the model to that, "balcony-in ???", for instance.

To properly encourage use of railing something like the following:

1. Leaning against metal railing.

2. Hand on stone railing.

3. Leaning over wooden railing.

4. Bent over railing.

SD continues to be infuriating however with uneven placement of bars/slats/pillars, and this can't fix its inability to have coherent ??????? past obstacles.
