Details:

The following snippet will in the Qt Gui on Windows 8 results in (1) a warning
for a missing font which is ok, (2) extent(4)=0 which should be the height
parameter, (3) font='*' which I guess is a substitute for the default font
name.


font   = 'bar';
h_temp = uicontrol( figure, 'Style', 'text', 'String', 'foo', 'FontName', font
);
extent = get( h_temp, 'Extent' )
font   = get( h_temp, 'FontName' )


I think the correct result is that font should be set to the actual default
font name and the extent(4) should be the actual/corresponding height (this
also seem to work fine on Linux).
