Character tuning

Final step: changing Content & font or Rendering later will undo character tuning.

Select a character on the canvas to nudge it and following characters.
dx 0, dy 0
Show per-character tuning

Nudges are stored on the selected character and apply from there onward. Later characters keep dx/dy 0 unless nudged too. Blank color uses black.
