#1851 gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar

[Chris Mayo]

With SciTE 3.6.6 Gtk+-3.20.8 on Gentoo Linux

Fix [63f891] for bug [#1831] set minHScrollBarWidth to minimum.height. Patch attached that fixes this for me.

scite --gtk-debug=geometry output with error:

Gtk-Message: gtk_widget_size_allocate:             GtkScrollbar 0 817 12 12, baseline -1

(scite:31575): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to underallocate ScintillaObject's child GtkScrollbar 0x28b27c0. Allocation is 12x12, but minimum required size is 46x12.
