Details:

 First case:
- call this command (result in fig_1.png):

close all; x=[-pi:0.1:pi]; h_p=plot(x,sin(x),x,cos(x));
h_l=legend([h_p(1),h_p(2)],{'sinusas','kosinusas'},'location',
'northoutside','Orientation','horizontal');

- then shrink figure vertically (result in fig_2.png);
- call 'legend' again:  

h_l=legend([h_p(1),h_p(2)],{'a','b'})

 Result (fig_3.png) was mess in plot layout. Seems that legend was placed in
position (in pixels?) when figure was in original size, and then axes follows
legend and expands vertically.

 Second case:
- execute this command (result in fig_4.png):

close all; x=[-pi:0.1:pi]; h_p=plot(x,sin(x),x,cos(x));
h_l=legend([h_p(1),h_p(2)],{'sinusas','kosinusas'});

- then expand figure vertically (result in fig_5.png);
- call 'legend' again:  

h_l=legend([h_p(1),h_p(2)],{'a','b'})

 Result in fig_6.png: legend jumps in to middle of plot window (original
absolute position of canvas in pixels?).
