[Scilab-Dev] get(h_matrix, prop) changed from 5.5.2 to 6.0.0, inconsistent in both cases

[Samuel Gougeon]

Hello,

In preparation to Scilab 6.0.2, some unitary or non-regression tests 
about graphics and GUI show some changes about the format of some 
properties:

test_run graphics plot2d_demo show_error
test_run graphics plot_demo show_error
test_run graphics bug_14042 show_error
test_run gui layer show_error

The first fixes simply propose to update the .dia.ref with the transpose 
of properties values
(e.g. https://codereview.scilab.org/#/c/20768 )

However, the analysis shows that the behavior of get(), that is also 
called from %h_e(),
changed from Scilab 5.5.2 to Scilab 6.0.0.

In both cases, and up to now, the size of the *get(h, prop)* output is 
not consistent when h is a vector of handles.

In *5.5.2*:, the output is always a row:
-->plot();
-->f = gcf(); Axes = f.children
  Axes  =
2 by 1 matrix of handles:
=========================
Axes
Axes

-->get(Axes, "visible")
  ans  =
!on  on  !
-->get(Axes*'*, "visible")
  ans  =
!on  on  !

In *6.0.0* and up to now (6.0.2-), the output is always a column:

--> f = gcf(); Axes = f.children
  Axes  =
2 by 1 matrix of handles:
=========================
Axes
Axes

--> get(Axes, "visible")
  ans  =
!on  !
!on  !
--> get(Axes*'*, "visible")
  ans  =
!on  !
!on  !

To me, the default size of the output should match the size of the 
matrix of handles.

Shouldn't it?

When the value of the property is not scalar, it is the user's 
responsability to
reshape the matrix of handles in a way that is compatible with the purpose.

Regards

Samuel
