   Detailed logic:
 
   1. Find the SliceNavigationController that has sent the event: this one defines our rendering plane and will NOT be
   rotated. Needs not even be counted or checked.
   2. Inspect every other SliceNavigationController
   - calculate the line intersection of this SliceNavigationController's plane with our rendering plane
   - if there is NO intersection, ignore and continue
   - IF there is an intersection
   - check the mouse cursor's distance from that line.
   0. if the line is NOT near the cursor, remember the plane as "one of the other planes" (which can be rotated in
   "locked" mode)
   1. on first line near the cursor,  just remember this intersection line as THE other plane that we want to rotate
   2. on every consecutive line near the cursor, check if the line is geometrically identical to the line that we want to
   rotate
   - if yes, we just push this line to the "other" lines and rotate it along
   - if no, then we have a situation where the mouse is near two other lines (e.g. crossing point) and don't want to
   rotate
