get it back when we lose it
- improved heuristics for measx/measy: instead of looking for "next" or "max"
on secondary coordinate, pick the one that's closest. I.e., if there's a
chance to just connect with x' = 0 or y' = 0, do it.
- mouse wheel on loop value now selects next/previous value
- corrected proximity calculation for measurements
- vec/frame/meas toggle now deselects, so that we don't accidently leave a
supposedly hidden item selected
