MATLAB is issuing a deprecation warning related to OpenGL rendering

[SeSodesa]

Description

When Zeffiro Interface is started up on a Linux machine, the following warning message is printed on screen:

Warning: MATLAB has disabled some advanced graphics rendering features by switching to software OpenGL. For more information, click here.

If one then clicks on "here", the following warning is shown:

Warning: the opengl function will be removed in a future release. Use the renderinfo function instead.

If this is not addressed, Zeffiro might become unusable with newer MATLAB versions in the near future.

Steps to reproduce

1. Open up MATLAB R2024b with its GUI active,

2. Start Zeffiro Interface with the command

   zef = zeffiro_interface ;
   

3. watch the warning message appear on screen.

Expected behavior

There would not be any warnings, or at the very last no deprecation warnings.

The mentioned problematic opengl function is called in the following files in the m/ folder:

λ grep --color -nP "opengl" m/**.m
m/forward_simulation/wave/compute_data_gpu.m:176:            set(gcf,'renderer','opengl'); set(gcf,'color',[84 90 112 ]/300);
m/zef_print_meshes.m:59:    set(h_fig_aux,'renderer','opengl');
m/zef_print_meshes.m:1409:    set(h_fig_aux,'renderer','opengl');

It then seems that the warning is printed when the ZI figure tool is being opened. It also seems like commenting the opengl lines in those files removes the warning without affecting Zeffiro behaviour in any way.
