These operators in sculpt mode affect hidden geometry which is undesirable. - bpy.ops.sculpt.face_set_edit - bpy.ops.sculpt.face_sets_init - bpy.ops.sculpt.face_sets_create(mode='SELECTION') - bpy.ops.mesh.paint_mask_extract() - bpy.ops.mesh.paint_mask_slice() This PR adds checks for hidden faces in these operators. For operator `bpy.ops.sculpt.face_sets_init` it also modifies the way face sets indices were generated so generated indices is unique. This is needed so new initialized face sets do not get same indices as hidden face sets. For generating unique face set index I have created a set container which stores hidden face sets indices. Before assigning indices to a face set it checks if it is already in set container, if it is then it'll keep increasing index by 1 until it is not in set container. Modifying Operator `bpy.ops.mesh.paint_mask_slice()` is little complex, it will not affect hidden geometry only when fill holes option is unchecked, because currently filling hole code does not take hidden geometry into account and because of this in some cases hidden part of geometry can be trapped inside mesh.
