  35 /*  FUNCTION
  36         Make a window visible. This function does not bring the
  37         window back into the visible area of the screen but rather
  38         switches it into visible state.
  39
  40     INPUTS
  41         window - The window to affect.
  42
  43     RESULT
  44         Success indicator. On AROS it's always TRUE.
  45
  46     NOTES
  47         This function is soure-compatible with AmigaOS v4.
  48         This function is also present in MorphOS v50, however
  49         considered private.
