  34 /*  FUNCTION
  35         Make a window invisible.
  36
  37     INPUTS
  38         window - The window to affect.
  39
  40     RESULT
  41         Success indicator. On AROS this is always TRUE.
  42
  43     NOTES
  44         This function is source-compatible with AmigaOS v4.
  45         This function is also present in MorphOS v50, however
  46         considered private.
