Follow-up Comment #32:

Plotting with "graphics_toolkit gnuplot" works for me on Windows 10 with your
changes.

I see the following two failing tests for "__run_test_suite__" with gnuplot
though:

D:\Repositories\Octave\test\octave-2019-01-27-16-56-w64_cdata\octave-2019-01-27-16-56-w64\mingw64\share\octave\6.0.0\m\image\getframe.m
***** testif HAVE_QT_OFFSCREEN; have_window_system ()
 hf = figure ("visible", "off");
 unwind_protect
   pos = get (hf, "position");
   assert (size (getframe (hf).cdata)(1:2), pos(4:-1:3));
 unwind_protect_cleanup
   close (hf);
 end_unwind_protect
!!!!! test failed
getframe: not implemented for gnuplot graphics toolkit
***** testif HAVE_QT_OFFSCREEN; have_window_system ()
 hf = figure ("visible", "off");
 unwind_protect
   hax = axes ("visible", "off", "position", [0 0 1 1]);
   verts = [0 0; .5 0; 1 0; ...
            0 .5; .5 .5; 1 .5; ...
            0 1; .5 1; 1 1];
   faces = [1 2 5 4; 2 3 6 5; 4 5 8 7; 5 6 9 8];
   fvc = [1 0 0; 0 1 0; 0 0 1; 1 0 1];
   patch ("vertices", verts, "faces", faces, "facevertexcdata", fvc, ...
          "facecolor", "flat");

   kk = 1;
   pos = get (hf, "position");

   for jj = [0.05 0.55]
     for ii = [0.05 0.55]
       rect = [ii jj .4 .4].*[pos(3:4) pos(3:4)];
       frame = getframe (hax, rect).cdata;
       assert (frame(:,:,1) == fvc(kk,1)*255);
       assert (frame(:,:,2) == fvc(kk,2)*255);
       assert (frame(:,:,3) == fvc(kk,3)*255);
       kk++;
     endfor
   endfor
 unwind_protect_cleanup
   close (hf);
 end_unwind_protect
!!!!! test failed
getframe: not implemented for gnuplot graphics toolkit


Should we skip these tests for gnuplot? New bug report?
