Expand grid when possible
In specific window sizes (happen to me on PinePhone with keyboard displayed) the grid could take more space, for example:
I think the clock could be "squeezed" to let the board take more space.
I tried playing with:
gsettings set org.gtk.Settings.Debug enable-inspector-keybinding true
(cd builddir/; meson compile) && GTK_DEBUG=interactive ./builddir/src/gnome-sudoku
I played around with vexpand, expand, and so on but I was unable to get the grid use more space.
Any idea? (Please note this is almost the first time I use GTK).
