Overview
Turning on valence will enable the display of double bonds.
Toggling valence_mode alters the positioning of double bonds (for representation as Lines)
valence_size alters the distance of double bonds
Note that bonds can be edited to be delocalized using Unond and Bond.
Examples
set valence, 0
#(no double bonds)
set valence, 1
set valence_mode, 1
#bonds inside
set valence, 1
set valence_mode, 0
#bonds centered
set valence, 1
#delocalized bonds
#(edited: see Bond)
valence_size alters the distance of double bonds, but behaves slightly different depending on valence_mode
| valence_size with valence_mode 1 | valence_size with valence_mode 0 |

Syntax
set valence, 0 # off
set valence, 1 # on
set valence_mode, 0 # centered
set valence_mode, 1 # inside
set valence_size, 0.1 # default: 0.06 # range 0 - ~0.5
# Editing bonds:
# In editing mode: select the bond using Ctrl-right-click, then enter:
unbond pk1,pk2
bond pk1,pk2,4
# 1: single bond, 2: double bond, 3:triple bond, 4:delocalized
