Function: stringheight

CALL:

height = stringheight(HWIN, fontname, fontsize)

DESCRIPTION:

INPUT: 

     fontname, fontsize:
         Font attributes

OUTPUT:

height any 
       scalar double (with integer value)

NOTES
      the 4tch component of Extent (=height) only depends on font and
      fontsize, not on fontweight of string
    -a-
    stringdimensions may be used as an alternative for get(h,'extent').
    -b-
    The advantage of stringdimensions is that it does not relay of a
    uicontrol object
    -c-
    When uicontrol is present, the extent method is generally faster
    -d-
    On a uicontrol extent returns a height value that is 4pts higher
