REVISION SUMMARY
  Some backends might not transmit scale information. For these save the scale
  value in the control file on change.
  
  Loading it from there is unproblematic in all three cases:
  
  - No scale value in file. Then falls back to libkscreen's value (default = 1).
  - Scale values are the same, that means backend transmits scale.
  - Backend does not transmit and scale is different, then prefer control file.
