recent dev does an incomplete redraw of the canvas on resizing, see the
attached plot for a side-by-side comparison of 8.0.91 and 9.0.0, after
resizing the initial plot window. octave-8 and octave-9 both built on the same
platform with the same libraries.


tk = graphics_toolkit
version = OCTAVE_VERSION
hg_id = __octave_config_info__.hg_id
[x,y,z] = sombrero;
surf(x, y, z)
title(['octave ' version]);
pause


octave-8 output:

tk = qt
version = 8.0.91
hg_id = bcb4becbcf94


octave-9 output:

tk = qt
version = 9.0.0
hg_id = 56223b5a01d4
