commit 10a7fde377d392088a2ef2303fd2aea2f8a50d2a
Author: Andrej Kacian <ticho at claws-mail.org>
Date:   Tue Jan 29 21:47:53 2019 +0100

    Properly free previous document from memory in litehtml's clear()
    
    We also call paint_white() earlier in redraw().
    This results in properly clearing the previously
    rendered html content when opening a different
    HTML part.
