  26 /*  FUNCTION
  27         Unlocks a previously locked layer for access by other applications
  28         or intuition itself.
  29         If a task has locked a layer multiple times it must unlock it
  30         as many times as well as locks nest.
  31         This functions does the same as layers/UnlockLayerRom()
