  31 /*  FUNCTION
  32         Releases exclusive access to a bitmap. Options for the unlocking
  33         process are given in a taglist. The possible tags are as follows:
  34             UBMI_UPDATERECTS (struct RectList *) - pointer to a series of
  35                 rectangle lists that need to be refreshed.
  36             UBMI_REALLYUNLOCK (BOOL) - if FALSE, the bitmap will not be
  37                 unlocked; only rectangle updates will be done.
  38
  39     INPUTS
  40         Handle - handle to the bitmap to unlock.
  41         Tags - a taglist as described above.
  42
  43     RESULT
  44         None.
